Java vs Javascript: What is the Difference?

Which one would win if they were put in a fighting ring - Java or Javascript? Well, sad to disappoint you but these two programming languages would most probably never make it to the ring as they have originally been designed to serve individual purposes. However, we still can find some similarities between Java and Javascript aside from their names. Let’s dig down!

 

Similarities Between Java and Javascript

 

  • Object orientation

 

OOP is a programming paradigm used to construct a software program into classes. 

Object-oriented programming is beneficial since it turns complex models into reproducible structures. It also lets you reuse the objects on other platforms. The object-oriented programming languages include Javascript, C++, Java, and Python. 

 

  • Front-end Development

 

Front-end development traditionally uses HTML, CSS, JavaScript to transform data to a graphical interface, therefore we may claim that Javascript plays an indivisible role for front-end development. Java, on the other hand, was used for front-end web development years ago using Applet technology. However, the technology is no longer secure and hence has been substituted by modern solutions. 

 

  • Back-end Development

 

Back-end development is the practice of connecting the database information to the browser. Java is one of the most widely used back end languages due to the Virtual Machine making its usage so versatile. In contrast, Javascript has a back-end runtime environment Node.js running on the V8 engine and executing JavaScript code outside a web browser.

 

  • Browser-wise

 

Both Java and Javascript are capable of running in a browser. Javascript runs in almost all contemporary web browsers. That’s the main reason why it is among the most preferred programming languages. Java, on the other side, runs in a browser through Java Applets, hence it may cause issues like security and cooperation.

 

Differences Between Java and Javascript

 

  • Usage Purpose

 

Javascript, being a scripting language, is used to develop client-side software programs including JS validation, while Java is mainly utilized in server-side development.  

 

  • Applications developed by Java VS Javascript

 

It’s important to realize that Java and Javascript create entirely different applications. The applications developed by Javascript mostly run in a browser, while the ones created by Java can not only run in a browser but also in a virtual machine.



  • Accessibility

 

As mentioned above, Javascript is used to create interactive and creative web apps, however, Java covers the development of Android applications, desktop applications, scientific, gaming applications, big data technologies, and more.

 

  • Compiled vs Interpreted

 

Javascript is an interpreted scripting language, meaning it can be interpreted by the browser, the client-side. While Java is a compiled programming language. It is compiled on the server before being executed on the client. So the main difference between them lies in the type of implementation. 

 

Key Advantages of Java

 

  • Independence 

 

Java is a completely independent programming language. All you need to do is to download and install the JVM on your computer and the language will run on any operating system.

 

  • Multi-Threading

 

The two languages are very different when it comes to handling the coexistence of several instruction sequences. Java uses multiple threads to execute tasks. It means that it can perform several tasks simultaneously. 




  • Security 

 

Java provides a security manager and security policy for each application it develops. It stops vicious attacks of viruses. Overall, we can claim that Java has fewer vulnerabilities compared to Javascript. Most of Java's weaknesses are due to its popularity.

 

  • Static vs Dynamic

 

Java is a static programming code. It means that the variable type is checked and verified before running the program, while Javascript is dynamic, which means that variable types can be verified during the program run.

 

Java Key Features include 

  • Access to great libraries

  • Portable due to being neutral and implementation free 

  • Great authentication techniques enable to create virus-free, error-free systems

  • The presence of Just-In-Time compilers

  • Highly distributed through the Internet



Key Advantages of Javascript

 

  • Client-side programming language

 

Javascript is again an object-based language, working with data rather than functions.   Unlike Java, Javascript is a scripting programming language which means it gets interpreted. The client-side programming language runs on the user's web browser without the need for the webserver. Javascript is utilized to create interactive web pages.

 

  • Robust Frameworks 

 

Javascript has a huge library of powerful frameworks which make working with Javascript ten times easier. The frameworks are design-adaptable, therefore they are quite popular among the developers. They also allow the programmers to code the application to be device responsive. Overall, we can claim that Javascript frameworks are preferable due to their countless advantages. 

 

  • Procedural Javascript

 

Javascript uses the best of procedural and functional programming, which makes it one of the most convenient languages. Procedural Javascript breaks down the program into smaller functions that can share data or even change the global data.

 

  • Concurrency

 

While Java uses multiple threads to execute tasks simultaneously, Javascript runs a single thread of execution in a queue known as the event loop. Both methods are efficient, though the former is faster and more optimal in executing multiple tasks in parallel. 

 

Javascript core features are the following! 

  • Based on functional style even while creating objects

  • Promise enables async processing

  • Prototype-based programming language, using prototypes instead of classes or inheritance

  • Supported by complex data types such as array, List, Maps, and more

 

Famous Brands that Use Java

 

One may feel overwhelmed by the number of worldwide famous companies that are developed by Java. Here they are

  • Uber

  • Amazon

  • Instagram

  • Spotify

  • Google

  • Netflix 

Most of those companies like Uber and Netflix claim that they have integrated Java for high performance purposes. Java derives benefits from the open source ecosystem and can integrate with high technologies. 

 

Famous Brands that Use Javascript

 

You may be surprised to find out that some of the above-mentioned companies also use Javascript to function. Here they are

  • Uber

  • Facebook

  • Google

  • Netflix

  • eBay

  • Paypal

 

Sum up

 

To sum up, Javascript is used to develop more interactive web pages and runs only in a browser, while Java is used in a wide range of enterprises including Mobile Applications, Desktop GUI Applications, Web-based Applications. The applications created by Java can run both in a virtual machine and a browser. 

Java is utilized for all server-side development, while Javascript is limited to client-side development.

 

In conclusion, the real statement should not be  “Java vs Javascript”.  The question is the difference between java and javascript and what applications are developed by each of them. 

 

Hopefully, this article clarifies the misconception between the two highly different but also similar programming languages helping the readers to make the right choice over what language they need. 




5+ Strategies to Find Developers in 2021

You've decided it: that crazy app idea you had in mind, you're going to turn it into a reality! The only problem is you don't quite know any programming language. So what are you going to do? Well, the only solution left is to find developers and give them the technical work. 

 

But hiring a developer can get messed up, especially if you're doing it for the first time. That is why we have created a guide of strategies to assist you in finding developers and choosing the best one of them. 

 

That said, without further adieu, let's jump into: 

 

How to Find Developers in 2021 

 

There are many ways you can find developers nowadays. In recent years, the IT-sphere became very popular, and many young people started doing their degrees in Computer Science or similar programs. Anyways, your developer might even not have a BA in that sphere as it is very easy to learn programming languages today. There are millions of online courses that give you the basic knowledge absolutely for free, and you can later dive deeper into it with seminars, offline courses, events, and so on. 

 

So the chances are that even some of your friends might do freelance development on the side, without you knowing it. But the question remains: how can you find a software developer? Now some of the most popular places to look for them are: 

 

Freelance developer platforms

 

The freelancing platforms have all types of professionals offering you their freelance services. So it is a place to check out. Here's a list of most-advised freelance developer platforms. 

 

 

Toptal is one of the most famous freelancing platforms. It has more than $200 million annual revenue, and it is growing by each year. Toptal is known for its highly professional freelancers. In fact, 90% of clients hire the first freelancer that Toptal introduced to them. To be short, you can get the best experts on this platform. The only thing to be aware of is that it might be a little pricier than you expected. 

 

If you ever heard about freelancing platforms, you should have heard about Upwork too. Upwork is the largest freelancing platform out there, and almost all freelancers have tried Upwork at least at one point in their career. Yes, there are many good freelancers on this platform, but beware: you might also come across some scam accounts. So, analyze the profiles and reviews before trusting your project to the freelancer. 

 

 

Finally, our last platform on the list is Ithire. You might not have heard about them as they are relatively new to the market, but we promise they are worth trying. The cool thing about Ithire is that it gathers only the best professionals and is focused on the IT sector only. It means you can get true specialists here.

 

 The other advantage of Ithire over the other platforms is that the prices here are pretty affordable. Plus, they have a project manager aligned with each freelancer to help you control the workflow easier. 



Developer Communities & Forums 

 

Another way to find a developer is by skimming through the places they gather: a.k.a. developer communities and forums. 

 

  • Stack Overflow 

 

If you want to find developers online, Stack Overflow is the best platform to do so. It is a website where programmers give questions and get answers regarding different aspects of their job. Although this is a place where people come to learn, you can use it for your purposes. 

 

  • GitHub 

 

GitHub is the largest development platform in the world. So there is no chance that a good developer is not a part of their community. What does this mean? You should check them 

out! 

 

  • Quora 

 

Finally, another place where developers come to solve their issues is Quora. You can look at some popular question threads and find a developer from there. Another thing you can do is to use Quora itself as a medium. Ask the community to help you to find a good developer, and you'll get a bunch of offers in an instant. 



Social Media 

 

Now, who does not use social media these days? It would be unfair not to mention some of the social media platforms in this list. So let's start with the most professional one: 

 

  • LinkedIn 

Yes, you guessed it, LinkedIn. LinkedIn is a professional platform where people mainly visit to update their professional portfolio or find new jobs. You can post a job offer on LinkedIn, briefly introducing your requirements and expectations from the potential developer. In a few days, you'll have pretty good CV-s sent to your inbox.

 

  • Facebook Groups 

 

Here you can find a large pool of developers for hire. Search for Facebook groups named "Freelance developers" or "All about developing" and request them to join the group. Once you're in, you can post a status saying you look for a good developer. Again, your inbox will be flooded with resumes. 

 

  • Twitter 

 

And the last social media platform you can use is Twitter. Shout out to the world that you need a good developer, and don't forget to use hashtags. Today almost everyone has a Twitter account, so the chances are high that this method will work. 

Developer Blogs 

 

You can use developer blogs to contact the writers and offer them your position. Here are some of the blogs that will come in handy: 

 

  • Medium 

 

Medium is a famous American publishing platform where you can find articles on almost all topics. You can search for development-related posts and contact the writer of the most acclaimed article. 

 

  • Free Code Camp 

 

This one is more of a learning platform. However, it also has a large community around it who constantly engage through online publications, forums, and chat rooms. 

 

  • Better Programming 

 

And finally, the last one on our blog list is Better Programming. Again it is used by programmers for learning purposes. However, you can bend the platform to match your needs and contact the writers who write the "how-to" articles. 

 

Referrals 

 

Old but gold referrals will never come out of fashion. You can find some of the best professionals simply with the help of your acquaintances and friends. Ask them whom they would advise, and you'll get to know various good professionals who can be trusted. 

 

So if you know that in your personal network, there might be people who have worked with awesome developers, ask them who they were. Most of the time, Referrals are the simplest and most affordable solution. 



Other Ways to Find Developers 

 

You can also go with the hard path and try to find developers with paid advertisements. However, it is pointless as there are so many free ways to get your job offer out there that paying for it is merely a waste of resources. 

 

However, almost all the strategies mentioned above were online. An offline way to do the same thing is to contact your local agencies and ask for face-to-face interviews. If you love the old manner of doing stuff, then this might work perfectly for you. 



Wrap Up

 

There are many ways to find developers, but the easiest one is to hire them through freelancing platforms. You can also skim through their communities and forums, check out their blogs, or find them through social media platforms. More conventional manners include referrals and offline meetings with local agencies. 

 

Whichever strategy you choose, make sure you conduct a meticulous interview to choose only the best of the best. All we're left to say is good luck!

Shopify Apps You Need in 2021

 

Today having your small business is pretty simple. You don’t even have to rent a place for it: all you need is a website. With companies like Shopify, you can build your eCommerce business in no time and start getting revenue. But the best part of it is that you can make your eCommerce outstanding and fun with the Shopify apps. No matter if you need additional functionality or analyzing tools, apps for Shopify got you covered. 




Top Shopify Apps

 

Starting from one of the best free Shopify apps: Lucky Orange. Have you ever wondered how your visitor interacts with your website? Is your visitor scrolling until the end, or does he stop on one of your texts and leaves? Understanding the strong and weak points of your eCommerce website helps you to increase your sales. And that is exactly what Lucky Orange offers! 

 

Lucky Orange gives you an overview of the way your visitors engage with your website. You can see all the mouse clicks, scrolling, stopping, and moving with their recordings. If you want to, you can even watch your visitors in real-time. 

 

It feels like you are standing beside them and watching their screen. Moreover, Lucky Orange also offers heatmaps that visualize your visitors’ clicks and scrollings. This way, you can easily see which are the hottest parts of your website.

 

Lucky Orange is perfect for improving your call to action, specific website sections, or pretty much anything on your page that prevents your visitor from purchasing a product.  

 

Finally, using the live view, you can see what challenges your current visitors have with your page and then help solve them instantly via the chat. In short, Lucky Orange is a perfect tool to analyze your visitors' actions and make changes to your website. 

 

The best part? It has a pretty decent free plan! However, if you decide to go with more advanced tools or have more than one website to track, you might need to switch to the paid versions. 

 

 

If you want to improve your customer experience, then you should try out Jebbit. Jebbit is another great Shopify app that allows you to make product match quizzes. It is a non-code tool, so you do not have to be technical to create an interactive product match quiz.

 

Now, you might wonder why do you need a product match quiz? Well, because it helps you to, later on, offer products which would better suit your visitors' needs, and the chances increase that they will buy from your website. 

 

You ask your visitors specific questions about them and the products they are looking for, and once they complete the quiz, they get a personalized list of products that would fit them the most.

 

In addition to this incredible tool, you also get the chance to create personality quizzes and surveys that can help you to know your customers even better! In the end, you can use Jebbit’s reports and analytical tools to understand how your customers interacted with your quizzes and what they love the most and the least about them.

 

Just like Lucky Orange, Jebbit comes with a free plan, but also has two more paid options to choose from. Their business plan costs $70/mo, and you can get the pro version for $300/mo. 

 

 

This one is our absolute favorite and is one of the must-have Shopify apps. It makes your website more fun and interactive by integrating a “spin-a-sale” game. When your visitor enters your website, a spinning wheel pops up, offering him a small game where he can win a sale or a special offer. It makes your visitor automatically more interested in your website, and even if he did not intend to buy anything, now he is more inclined to do so. You can include different options in the spinning wheel, such as a 20% off, buy one get 2nd for free, or pretty much any other discount offer you want. It instantly raises the curiosity of your visitor and helps you to increase purchases. 

 

But the best part is yet to come. Although it would be hard to understand from its fun appearance the main purpose of this app is to serve as a subscription pop-up. If you put a simple and boring pop-up menu for your visitors to provide their email addresses, chances are high they would simply skip it or even leave your website annoyed with the sudden pop-up menu.

 

However, spin-a-sale makes it seem like a game, and your visitors do not think twice about providing their emails. They know that you need the email for sending them their discount coupon, so they will give it to you without much bothering. 

 

Finally, you can fully customize your spin-a-sale app by putting the exact offers and discounts you want. Unfortunately, Spin-a-Sale does not have a free plan, but their pro plan comes with just $9.99/mo, and you can get the premium version with only $24.99/mo. 

 

 

From Spin-a-Sale to Bold Upsell: another one from the must-have Shopify apps costing just $9.99/mo. 

 

Let’s imagine a scenario. You are in one of your favorite shopping websites, scrolling through the Summer Sale section and choosing a pretty affordable pair of sandals. You add it to your cart and are ready to purchase it when a sudden pop-up bar appears telling you that you can buy a prettier pair of sandals by adding up only $10. Why not right? 

 

You agree to upgrade your purchase order, and then another menu pops up, telling you that your sandals would look the best with a hair bandana that has just the same color as your shoes! What a deal, you think, and add that too to your cart. In the end, you do not even notice how the sandals you found from just $10 turned into a $30 purchase of a prettier pair and a hair bandana. Although you spent a little more, both you and the eCommerce owner are satisfied. 

 

If you want to integrate similar pop-up menus into your eCommerce, Bold Upsell is the app that allows you to do so. It offers your customers upgraded or complementary products to the ones they purchased. It also gives them the chance to easily remove or add up those products to the cart. 

 

As we have mentioned, Bold Upsell’s starter plan comes with just $9.99/mo. However, their Pro plan costs $59.99/mo, so it depends on how many views per month you want to get. Anyways, all of the plans come with a 14-day free trial, so you can test it out before you buy it. 

 

 

Last but not least, introducing to you Tidio: another one of the best free Shopify apps. Tidio takes all your live chat messages, emails, and Messenger texts to one place. You can answer them all from one platform! It also gives you an option to answer many of your customers’ questions automatically. It makes your response time considerably shorter. 

 

The best part about Tidio is that it is very simple and takes just 30 seconds to install on your Shopify. Tidio has a free plan, but if you decide to go with more premium features such as live type preview or seeing a list of live visitors, you can choose from their Communicator or Chatbot plans. 



That is it for today. We hope you have enjoyed our list of top Shopify apps for 2021! Although all of these apps are fun and easy to use, creating and maintaining a Shopify app is still a tough job. If you think you do not have enough time for it, find freelance Shopify developers here and focus on scaling up your business instead. 

Top 6 Wordpress Plugins to Use in 2021

Want to improve your website in 2021 with some of the best WordPress plugins? Great decision! But in this large pool of options, which plugins should you choose? 

You might wonder: why choose at all? There are more than 50000 WP plugins out there, so why not download all the ones you want? The answer is because it will hurt your website. 

You might think having hundreds of SEO, security, backup, and caching plugins will only make your WP boost its performance. But the complete opposite is true. Having too many plugins significantly decreases your website's performance. 

It also makes it harder to keep your website secure. If you have many plugins, it will become harder to manage them and make sure they are all updated. However, you can't really miss the updates either. One of the ways hackers leak into your account is through old plugins. 

The good rule of thumbs is not to get more than 20 plugins for your website. This number lowers down even more if you host your website on shared or low-budget cloud hosting. In these cases, you should not go over five plugins. 

All of this makes it extremely hard to choose the right plugins. That is why we have collected the best WP plugins of 2021 to make your job a little easier. 

But before we jump to our list, as usual, let's have some terms explained for the complete beginners: 

What are WordPress plugins? 

 

WordPress plugins are downloadable extensions to your website that add up its functionality. They are written code that helps to expand the existing functions or add completely new ones. 

There are different plugins that you can download for your website. From SEO plugins to security and caching ones, WordPress offers both free and premium plugins for any aspect of your website. 

 

Where do you find WordPress plugins? 

 

One of the most popular places to find a WP plugin is the official WP plugin directory. It is the official WordPress website for getting open-source and free plugins. If you are a developer, you also can add your plugin to the WP plugin directory. 

Another great platform to find WP plugins is  CodeCanyon. It is a place where you can find a large pool of premium and exclusive plugins. Here you can find many high-quality plugins, but do know that none of them are free. So this option is a good one if you have enough money to purchase your plugins instead of downloading them for free. 

In addition to this, you might also find plugins in the personal websites of developers. Many developers have started to contribute to the community by adding their plugins. However, sometimes they choose to offer them not in the traditional WP plugin directory but on their own websites. 

So this might be an option too! However, beware that not all of these plugins can be trusted. Read some reviews, and make sure the plugin is secure before downloading it. If the website looks quirky and gives you a bad feeling, it might be better to avoid it.  Now that we got all the main concepts cleared out, let us rush straight to the: 

 

Must-have plugins for WordPress in 2021 

To make your job a little easier, we have divided our article into main parts: the free WordPress plugins and the premium ones. Assuming that most of you will be more interested in the free plugins, we will start there. 

Best Free WordPress Plugins 

Here are our best picks among the free WP plugins: 

 

 

Yoast SEO's chief mission is to make SEO available for everyone, no matter big or small. That is why even their free Yoast SEO version has many helpful features that will push you upper on the SERPs (Search Engine Result Pages). 

One of the ways Yoast SEO makes your website more SEO-friendly is by optimizing your text. Yoast SEO conducts an SEO analysis and readability analysis. They point out the ways you can improve your text. 

Yoast SEO helps you with your keyword research by suggesting focus keyword options. After you enter your focus keyword, the plugin analyzes the text and tells you how to improve your keyword usage. 

The best part about Yoast SEO is that their feedback is visually simple. You get a red color if you are doing poorly on the SEO. A yellow is when you are somewhere in the middle, and green is for good. 

The readability analysis tells you how easy your text is to read. Yoast SEO might suggest you shorten some of the sentences or write with more simple words. 

In addition to the text analysis, you also get to preview how your page would look on google, add meta tags and descriptions, do some technical configurations, and much more. 

Here, you can find all of the features for both  Yoast SEO-free and premium versions.  Although the premium version comes with many additional tools, the free version is also pretty good at SEO-optimizing your page. 

 

 

From SEO to Caching. Before we start talking about the plugin, let us first of all figure out what caching is.  

The WordPress core sends a PHP query to the database, which then sends back the requested information. Later on, WordPress uses this data to create an HTML page for the user.

This entire process takes a lot of time, and it influences your site's load speed. Not to make your visitors wait so much for the data to be displayed, you can use caching plugins. 

The caching plugin creates a copy of your HTML site which is called anytime the web user enters your page. It makes the rending time faster, decreasing the time your users wait for your page to load. 

That said, let us take a look at one of the most popular caching plugins: the WP Super Cache. With WP Super Cache, you can improve your website performance and speed significantly. 

If your website is having too much daily traffic or is too slow, WP Super Cache will solve it. By creating HTML files coming directly from Apache, it lightens your website. You can read how to set up the WP Super Cache here

 

 

We talked about SEO and performance so far, but it all fades away if your website is not secure. You need to keep your page safe for your users, especially if they trust their credit card credentials, login passwords, and any other personal information to you. 

And even if your clients do not share this type of information, you still cannot afford to have your website hacked. That is why we suggest downloading one of the best free WordPress plugins, the Wordfence Security. 

Wordfence Security comes with a WP Firewall, Security Scanner, Wordfence Central, Login Security, and other security tools. The firewall helps to find and block all the attacks. It also identifies which IP addresses are the most suspicious and automatically sends them to the blacklist. 

With WordFence Security, you can also conduct security checkups that will check your plugins, core files, URLs, and the website in large to find if there are any malicious codes added. 

The login security enables you to add Captcha to your page to protect you from bots that try to log in. You can also add two-factor authentication (2FA) to make sure only the trusted members log in. 

These are only a few of WordFence Security features. It provides much more, and the good news is for free! Of course, WordFence Security also has the premium version for more advanced tools, but the free one still has a lot covered

Best Premium WordPress Plugins 

Now that we have discussed some of the best free plugins, it is time to look at the premium ones. If you have some money to spare, then this section is for you! Of course, all of the plugins we mentioned above also have their premium versions, but we won't talk about them here to not bore you out. 

Instead, we have created a new list of exciting and fun WP plugins for you to take a look at! Let's start with the: 

 

 

One of the essential parts of your website is the contact us section. If your visitors want to connect with you somehow, they should have a clear understanding of how to do so. 

If you leave your email and phone number somewhere at the end of your website, most of your visitors will simply give up on the idea of contacting you. Moreover, writing an email requires a lot of hassle, and many of the visitors will skip that part. 

So, what should you do instead? Create user-friendly forms, which will make contacting simple. Here is where the WP Forums plugin comes in. With its drag-and-drop builder, you can easily create forms, and embed them in your website. 

It also comes with pre-built templates that simplify your work even further. You get instant notifications when users respond to the forms, and the forms are also 100% mobile-friendly. 

With WPForms, you can create contact us forms, surveys, registration forms, and even payment forms. It's all simple and easy! If it seems interesting for you, check their pricing page to learn about their plans. 

 

 

Regularly backing up your website is a must. You must be sure that you have a saved version of your WordPress in case the worst happens. What if your page gets attacked by hackers? Will you have a backup version just in case? Well, you should. And the BackupBuddy will help you with it. 

With BackupBuddy, you can back up your entire website in no time. It collects all the data needed to run your website and wraps it up in a zip file. This way, when wanted, you can restore your website from scratch.

The BackupBuddy also allows you to schedule your backups. You can set up automatic backups that will run daily, twice a day, weekly, bi-weekly, monthly, and so on. When the backups are finished you get notified immediately, so that you can take care of them. You can learn more about the plugin and purchase it here. 

 

We end our list with a builder WP plugin. A builder plugin simplifies website building and helps you to create pages easily. 

The Beaver Builder allows you to experiment with your creativity and build professional websites with no coding. The simple drag-and-drop feature makes building pages fun and gives you total control over your website. 

With Beaver Builder, you can easily design your page how you want it to look in the front-end. The live, front-end editing feature allows you this. The way you build it is the way you will see it: all simple.

 

The Beaver Builder works with almost all of the themes and is also mobile-friendly. It has Woocommerce support and is SEO-optimized: what else do you need? 

So if you want to build your websites fast and easy, get the Beaver Builder plugin and enjoy the process. By the way, if you need the free alternative for this plugin, you can also try Elementor, which is also a very popular WordPress builder. 

That was it for today. 

We listed the best free and premium WordPress plugins for 2021. However, even with the plugins, website creation and management can be tiring for absolute beginners. If you think you don't have enough time for that, hire a freelance WordPress developer, and let him do the work for you! 



Top 5 HTML5 Tips and Trick: Major Features to Know

Want to create an attractive website? You don’t have to hire an expensive UI/UX designer for that. With HTML5, CSS and JavaScript, you have enough tools to make your website unforgettable. 

In this blog entry, we are giving you a complete HTML5 tutorial. It will help you to make your website even better! However, if you don’t have enough time, you can hire professional html5 developers on our website.

Before we jump into our HTML5 tutorial and explore the coolest HTML5 tips and tricks, let’s understand how HTML5 is different from HTML.  

 

What is new in HTML5 ? 

 

First of all, let’s take a look at the new features of HTML5 and understand in which aspects it is different from HTML. Here are some of the major factors: 

 

Audio and Video 

Storage 

Support of Web Browser 

Vector Graphics 

Usability 

 

With HTML 5, you can embed media without third-party plugins. You can also use canvas and svg to use vector graphics without additional technologies. When it comes to storage, with HTML5 you can use application cache, web storage, and web SQL database. Compare it to HTML with just the browser cache, and the advantages are visible. However, not all web browsers support the new HTML5 features. Nevertheless, HTML5 is still a preferred version as it is easy to use and has a simple syntax than HTML. 

 

Now straight to the: 

Top 5 HTML5 Tips and Tricks

Audio and Video Tags 

 

The concept of media was foreign to HTML. So one large leap that HTML5 makes is introducing us to audio and video. It is one of the fundamental HTML5 features, as it rids you from the headache of using third-party plugins. 

 

Audio 

 

Now, you can use HTML5’s <audio> tag to embed your audio directly into your website. However, currently only the most popular and recent browsers support HTML5 audio. So, it is better to use some type of backward compatibility: 

 

<audio autoplay="autoplay" controls="controls">

    <source src="file.ogg" />

    <source src="file.mp3" />

    <a>Download this file.</a>

</audio>

 

Keep in mind that Mozilla and Webkit do not get along with this new audio format yet. You will need to use the .mp3 extension for the Webkit browsers, while Firefox will ask you for a .ogg file. In short, for the time being, try to maintain two versions of your audio to avoid issues. 

 

Also, note that Safari will not recognize the .ogg format when loading your page switching to the mp3 version. 

 

Video 

 

Just like the <audio> tag, HTML5 also provides the <video> tag for embedding your videos to your website without third-party plugins. The good news is that YouTube announced that it added an HTML5 video embed for YouTube videos, which makes embedding even easier! Of course, you should make sure that your browser supports this new format. 

 

Safari and Internet Explorer 9 will support the H.264 format video, as the Flash Player can read it. However, Firefox and Opera only support the Theora and Vorbis formats. So, just like with audio, it is better to have both formats for your HTML5 videos. Here is an example of using the <video> tag: 

 

<video width="320" height="240" controls>

  <source src="movie.mp4" type="video/mp4">

  <source src="movie.ogg" type="video/ogg">

Your browser does not support the video tag.

</video>

 

 

The Canvas Element 

 

Another creative way you can use the <canvas> element is by making animations with it. With the mix of the <canvas> element and JavaScript, it is now possible to create pretty animations without needing the Flash: right from your web browser. If you want to give it a shot, here is an HTML5 tutorial for making animations with canvas

 

One thing is for sure: animations and similar visual enhancements have always attracted the attention of visitors. So if you want to take your website’s user experience to another level, you need to give it a try. 

 

Another key element of HTML5 is the <canvas> which has influenced the wide usage of Adobe Flash in many websites. You can use the <canvas elements for drawing graphics with different colors and shapes by using scripting (usually JavaScript). It is a container for visual graphics. Here’s an example of its usage: 

 

<canvas id=”myCanvas” width=”200″ height=”100″ style=”border:1px solid #000000;”>

</canvas>

 

 

Voice Recognition Feature 

 

Another cool feature of HTML5 is its voice recognition tool. With the new speech recognition API, your visitors can browse through your website using voice commands. JavaScript has access to your browser’s audio coming from speech recognition API. It can then convert the audio to text and complete the directives. Of course, this will only work if the voice is decipherable. Here’s a visual representation of the process: 

 

 

At this moment, the voice recognition feature of HTML5 is supported only by Chrome. But because Chrome has a booming 63.3 percent of market share, it is not that sad. Your voice recognition feature would be available to the majority of your visitors. It will make your website unique and help it to stand out. 

 

Here’s how you voice recognition to a text input: 

 

<input type="text" x-webkit-speech />

 

 

The Ability for Visitors to Customize Background or Text Color 

 

 

One of the coolest features of HTML5 is that you can have your customers choose the background and text color they want your website to be in. It will add an extra layer of fun to your website and will enhance the user experience. Here’s the extra code you need to add to your website to make this possible. 

 

 

<select name=”clr” onchange=”document.bgColor=this.options[this.selectedIndex].value” size=”1″>

    <br>

    <option value=”black”>black

        <option value=”orange”>orange

            <option value=”flamingred”>fuschia

                <option value=”lightyellow”>light yellow

                    <option value=”green”>green

                        <option value=”cyan”>cyan

                            <option value=”yellow”>yellow

                                <option value=”red”>red

                                    <option value=”white”>white</option>

</select>&nbsp;&nbsp;Background Color

 

<br>

<select name=”clr” onchange=”document.fgColor=this.options[this.selectedIndex].value” size=”1″>

    <br>

    <option value=”black”>black

        <option value=”orange”>orange

            <option value=”flamingred”>fuschia

                <option value=”lightyellow”>light yellow

                    <option value=”cyan”>cyan

                        <option value=”yellow”>yellow

                            <option value=”red”>red

                                <option value=”white”>white</option>

</select>&nbsp;&nbsp;Text Color

 

 

Help your visitors to enjoy your website to the fullest! 

Map Images 

We end our HTML5 features list with the map images. With this cool feature, you can make different areas of your image clickable. For instance, you can have a map of your country and link various restaurant websites to specific areas. This way, when your visitor clicks on those areas, she will be led to the local restaurant’s website! 

 

How do you do that? You simply need to mention the X and Y coordinates in the <area> element which is in the <map> element. Here’s an example: 

 

 

<h1 style="text-align:center;">The 7 Continents</h1>

 

<h4 style="text-align:center;">&#10148; Click on the dots in the image to go to a continent section</h4>

 

<map name="continents_map">

 

 <area shape="circle" coords="70,70,10" href="#north_america">

 

 <area shape="circle" coords="133,185,10" href="#south_america">

 

 <area shape="circle" coords="270,137,10" href="#africa">

 

 <area shape="circle" coords="292,44,10" href="#europe">

 

 <area shape="circle" coords="469,201,10" href="#australia">

 

 <area shape="circle" coords="374,65,10" href="#asia">

 

 <area shape="circle" coords="340,267,10" href="#antartica">

 

</map>

 

<figure style="text-align:center;">

 

    <img usemap="#continents_map" src=https://bit.ly/2bgFrvL width="600px" />

 

    <figcaption>World Map</figcaption>

4 Important Reasons to Use PHP

PHP is one of the most popular languages in programming. It has been used for already two decades but remains one of the most popular and scripting languages. With PHP having this many supporters and practitioners, you might wonder: what’s the deal? In this blog entry, we will tell you why everyone loves PHP and why you need to use PHP too. 

 

Why use PHP? 

 

As we have mentioned, PHP is a pretty popular language among developers. It is chiefly practiced in web development and is one of the best choices in the field. At first, developers used PHP for getting dynamic and user-friendly websites. Currently, PHP is mostly used for building and maintaining server-side applications.

 

So, you can use PHP for a bunch of purposes. It works for building desktop applications, and PHP5 even supports object-oriented programming. So, PHP is open for a variety of usages, and it’s up to you to bend it the way you want. 

 

There are innumerable reasons why to use PHP. Just think about it: the two of the most famous software, Facebook and WordPress, were written using PHP. WordPress has the largest share in the CMS market and a large community of developers and supporters. 

 

And Facebook? It is useless to mention what a huge role it plays among social media platforms. Having both software on PHP already adds up a lot to this scripting language. 

 

But, let’s not jump ahead of us. Here are: 

 

Four important reasons to use PHP 

 

Cost-efficient solution 

 

One of the main benefits of PHP is that it is open-source. It means you can considerably cut off your expenses by using this free-scripting language.

 

Not only is PHP free, but also most of the development tools connected with it are. In short, PHP will help you to save your development budget. 

 

Famous websites using PHP 

 

Another reason to trust PHP is that some key websites have done so and did not regret it. Here are just a few names of PHP-using websites: 



  • Wikipedia: Yes, that omniscient website that you refer to for pretty much anything is using PHP and MySQL/MariaDB as their database backend. 
  • Tumblr: The meme-community that has more than 555 million monthly visitors switched to PHP7 in 2016.
  • Slack: Finally, one of the most famous professional communication platforms with over 3 million active users in a day deploys PHP. 

 

Flexible code 

 

If you are wondering how to make a PHP website, the answer is: easily! PHP code is flexible and easy to use. But more than that, it is also a cross-platform solution. You can run it on Windows, macOS, Unix, and Linux. 

 

Moreover, the PHP backend is supported on Apache, Microsoft IIS, Caudiom, and many other chief servers. All of this makes it easy to build cross-platform applications and not worry about compatibility errors. 

 

Faster loading speed 

 

We will conclude our benefits of PHP with this one: better loading speed. PHP is currently making your website load around three times faster than Python does. Getting a high load speed is essential for your SEO, user experience, and conversion rate. So, having a scripting language that does not decrease your load speed is a significant advantage.

Figma Pricing

What is Figma?

In our days, the digital world seems to take over new heights. Also, because of Covid-19, many people started to work online and some businesses started to operate remotely. Hence, a space where the teams would work remotely, yet efficiently, was vital. This is also when we hear many people working collaboratively on Figma or at least using the tool recently. 

People in the digital world seem to use the word “Figma” more and more often. So, how should one define Figma? What is it? 

Figma Definition: 

To put in short, Figma is a design and prototyping tool. As it is clearly stated on the website, “Figma brings product teams together for a faster and inclusive design workflow”. Generally, it is a tool that assists teams working remotely or not in creating, testing and handing in intuitive designs from the very beginning to the end. 

There are some other platforms similar to Figma, such as Sketch, Adobe XD and InVision, where designers turn their ideas into reality. However, there is a key factor with which Figma stands out from the rest of the tools similar to it. It allows a group of team members to work on a single project at the same time, enabling fast and effective shipping of projects. Moreover, Figma is available on Macs, Windows PCs and Linux machines, which makes the tool accessible for a wider group of people. Let’s say, digital designers have Macbooks they work on, developers use Linux or PCs, and the client has a PC. Assuming this is the case, everyone can easily access Figma! 

Figma’s software has a number of advantages over the other existing tools and platforms. To know more about them, go over the list below:

Work Fast! It enables the designers to use Figma easily and quickly, saving time on installing, saving files or exporting them. You would agree that even a few seconds matter to get the projects done faster!

Work with a team! This tool gives the opportunity to share the file with the team members and work on it collaboratively, no matter in the office or thousands of kilometers distanced. Figma ensures comfort for the teams!

Work in tandem! Figma is perfect for doing two different works alongside. You can design and prototype accordingly, receive feedback for the design or test those as much as you like. It is an effective tool for design and prototyping, boosting team’s productivity. 

Who is it for?

There might be an impression that digital designers are the only ones who use Figma. However, Figma’s design is for everyone. 

It enables designers to create, craft and form digital design from the beginning to the end. Designing, wire-framing, prototyping is all available with Figma, and digital designers showcase their excellency in their field. 

Although it is a tool largely used by digital designers, product owners and developers also easily use or share the digital design project files on Figma. Other team members can easily work on the files, give feedback, leave comments, and extract the ready files. 

Thanks to its simple layout, even non-specialists can easily navigate around and grab the necessary files from it. So, everyone can use Figma!

 

Figma Pricing

Like many other tools or platforms, Figma Pricing is designed for different needs. There are three options: starter, professional and organization.  

If you choose a starter option, it will give you a free subscription. You can have up to 3 projects with 2 editors. It still gives you unlimited cloud storage and unlimited free viewers. Starter option is suitable for beginners, just making their first steps into digital design. 

If you choose a professional option, it will cost you $12 per editor per month billed annually or $15 per editor month-to-month. Compared to the starter option, the professional option has more advantages. You can have unlimited projects and version history, custom file/user permissions, invite-only private projects, and most importantly, shareable team libraries. This is quite a beneficial package for those who are experienced and want to use all the privileges of this design and prototyping tool.  

If you choose an organization option, it will cost you $45 per editor per month billed ONLY annually. This option is mostly suitable for bigger companies specialized in digital designing. You will have all the features available in the professional option, but also private plugins and plugin administration, shared fonts, SSO + advanced security, as well as design system analytics. The key advantage of this option is the availability of admin and security features. It gives opportunity to larger teams to organize their work and experience with Figma in a higher level of comfort. 

In Brief: 

Figma is a design and prototyping tool designed for digital designers and eased enough to be used by non-specialists while sharing or extracting files. It is accessible to all machines and is customized for beginners, smaller or bigger teams, offering three subscription plans.

Top 6 React Interview Questions and Answers for 2021

React.js interview questions may seem quite troublesome if you have not taken your time preparing for the BIG day. Slowly but steadily, React is becoming one of the most influential Javascript frameworks in the marketplace. Therefore the demand for React js developers is increasing daily. 

So, if you desire to find a job as a front-end developer or find a front-end developer for your project, get prepared with these React Interview Questions beforehand and achieve your objectives! 

 

Generic React Interview questions

 

What is React?  

React is a front-end JavaScript library developed by Facebook in 2011. Its principal purpose is to grow compound and interactive web and a  mobile User Interface. It is based on a component approach and helps to expand reusable UI components. 

The main features of React js are 

Virtual DOM

Server-side rendering 

Unidirectional data flow

React JS makes it altogether easy to write User Interface test cases. React conveniently incorporates other frameworks such as Angular, Meteor. 

It is essential to keep in mind that React is just a library rather than a fully developed framework. The library is wealthy, but don't worry, you have plenty of time to do your research.



What is JSX?

JSX stands for JavaScript XML. JavaScript XML is a file used by Reach employing the full potential of JavaScript with HTML-like syntax. The HTML file is accessible to understand, have a look below. 

 

render(){

    return(     

          

<div>

             

<h1> Hello World from Edureka!!</h1>

 

         </div>

 

    );

}

Browsers cannot read a JavaScript XML since they only read JavaScript objects. Therefore, JSX files get converted into a JavaScript object by JavaScript transformers such as Babel for browsers to read it. 

 

After such general questions, the interview will turn into a more technical discussion.

 

 

Is there any difference between Real DOM and Virtual DOM?

 

Yes, there certainly is. Real Dom is slow and creates a new DOM every time an element gets updated. Virtual DOM is faster and updates JSX if an element gets updated. Real Dom can directly update HTML, while Virtual Dom cannot, however Virtual DOM manipulation is much easier compared to Real Dom expensive manipulation. 

So, we can say that Virtual Dom is originally the copy of the Real DOM. It is a light JavaScript Object, a note tree that lists the elements, the attributes and content as Objects. The Virtual DOM works in three easy steps. 

Whenever any fundamental data changes, the entire User Interface gets re-rendered in Virtual DOM representation.

The difference between the previous representation and the new one is calculated. 

After the calculatioReact.js interview questions may seem quite troublesome if you have not taken your time preparing for the BIG day. Slowly but steadily React is becoming one of the most influential Javascript frameworks in the marketplace, hence the demand for React Certificate is increasing daily. 

So, if you desire to find a job as a front-end developer, prepare with these React Interview questions beforehand and achieve your dream!

 

What is Props? 

Props stand for properties in React. They are purely fixed read-only components that are always passed down from the parent to the child components and never back. A child component can never send a prop back to the parent. It guarantees the unidirectional data flow of React.

 

What is a State?

 

States are the core feature of React components. They are a source of the data and are mutable, unlike props. In a word, states directly determine components rendering and behavior. 

 

There is an underlying difference between Props and States. Props acquire initial value from parent components, while states do not. Meanwhile, the parent component cannot change its value in States, but it can in Props. The same goes for the child component as well. Both States and Props set the default insight component. The insight component is unchangeable in Props, while it can undergo mutation in States.

 

Describe the React js lifecycle

React defines components as classes or functions. Components defined as classes provide more features. You need to extend React.Component, to define a component as class. Render is the only method that must be defined in a React.Component subclass. All the other methods are optional. Have a look!

 

class App extends React.Component {

render() {

return (

<div className="App">

<h2>Hellow World!</h2>

</div>

);

}

}

Each component has several “Lifecycle Methods” that can override to run codes throughout the entire process. 

 

Lifecycle methods are divided into four classes: 

Mounting

Updating

Unmounting

Error handling

 

Mounting includes constructor(). Constructors are used for two main reasons:

Starting a local state by assigning an object to this.state.

Binding event handler methods to an instance.

 

static getDerivedStateFromProps() is called right before the render method. This method exists in rare usage cases when the state depends on whether props will change over time. This method is fired on every render, in contrast to UNSAFE_componentWillReceiveProps, which only fires when the parent causes a re-render and not as a result of a local setState.

 

render()

The render method is the only required method in a class component. When it gets called, it examines this.prop and this.state and returns one of the following types. The render function should not change the component state. It should return the same function every time it is invoked.  

The render function does not interact with the browser, but if you need it to interact, simply perform your work in componentDidMount() or the other lifecycle methods instead.

 

componentDidMount()

ComponentDidMount() is supplicated after a component is mounted. This method is a good place to set up any subscriptions. However, in that case, you should unsubscribe in componentWillUnmount(). SetState() can immediately be called in componentDidMount(), which will trigger another rendering. However, it will happen before the screen is updated by the browser. Therefore, the users won't see that the render has been called twice. 

 

shouldComponentUpdate()

ShouldComponentUpdate() is used to let React know if the state or props current change has affected the component’s return or not. The default behavior must re-render on every state change.

When shouldComponentUpdate() returns false, componentDidUpdate(), UNSAFE_componentWillUpdate, render() are not called. However, React may later treat shouldComponentUpdate() as a hint rather than a directive and returning false may still result in a re-rendering of the component.

 

shouldComponentUpdate()

ShouldComponentUpdate() is used to let React know if a component’s return is not affected by the state or props current change. The default behavior must re-render on every state change. 

When shouldComponentUpdate() returns false, componentDidUpdate(), UNSAFE_componentWillUpdate, render() are not called. However, React may later treat shouldComponentUpdate() as a hint rather than a directive and returning false may still result in a re-rendering of the component.

 

getSnapshotBeforeUpdate()

getSnapshotBeforeUpdate() enables your component to acquire some information from the DOM before it changes, passing any value returned by this lifecycle as a parameter to componentDidUpdate().

componentDidUpdate()

componentDidUpdate() is called immediately after updating occurs. This method is not called for the initial render.  ComponentDidUpdate() can be used for operating the DOM when the component has been updated. You can also do network requests as long as you compare the current props to previous props. 

Unmounting

This method is invoked when a component is being removed from the DOM:

componentWillUnmount()

componentWillUnmount() is called immediately before a component is unmounted and destroyed. 

Emergency cleanups such as invalidating timers, canceling network requests, cleaning componentDidMount() subscriptions should be performed straight away. 

SetState() should not be called in componentWillUnmount() because the component will never be re-rendered. Once a component instance is unmounted, it will never be mounted again.

Error Handling

Error Handling Methods are invoked when there is an error during the lifecycle methods, in the construction of any child component, or during rendering. 

static getDerivedStateFromError()

This lifecycle is called when a descendant component throws an error. It receives the error that was thrown as a parameter and should return a value to update state.

GetDerivedStateFromError() is called during the “render” phase, so side-effects are not permitted. To have side-effects permitted use componentDidCatch(). 

With the componentDidCatch(), the lifecycle is supplicated after a descendant component throws an error. It receives two parameters:

error- an error appears

info - An object with a componentStack key containing information about which component threw the error.

ComponentDidCatch() is called during the “commit” phase, so side-effects are permitted. It should be used for things like logging errors.

All in all, you will have to focus on both basic interview questions and more technical ones such as React component questions, React Redux, and Router Interview questions to pass the stage. Don’t stress much, take your time, and go for it. 

Good luck!!
