Shopify VS Magento: Which Is Better in 2021?

Magento VS Shopify

Today starting your business is easier than ever. All can be done in the online format. You no longer have to rent a place if you are just a beginner. All you need is a website! But that is easier said than done. Creating a decent eCommerce website is a big deal, and if you do not take it seriously, it will be a failure. But what do you need for a good eCommerce website? A good eCommerce platform. 

 

Today, the most significant players in the market are Shopify and Magento. Both of them are great platforms for building your eCommerce business. However, it would be best if you chose them depending on your business needs. To make your job easier, we will have a quick Magento VS Shopify comparison to understand which is the best eCommerce platform for your business. 

 

Magento VS Shopify 

 

Before we dive into the feature comparison, let’s understand what each of these platforms is. So here is a quick recap for the beginners! 



 

 

 

Shopify 

 

Shopify is a CMS platform that helps anyone to create their online store and sell products. Shopify CMS was founded in 2008 by Tobias Lütke, who needed to sell Snowdevil snowboards. When creating the website, he realized how challenging it was to set up an online store. There was no easy-to-use platform for it. So, Tobias decided to create it, and that is how Shopify was born. 

 

Magento 

 

Magento was founded in 2007 by Roy Rubin and Yoav Kutner. It was initially part of the Varien project and was created while Rubin was still studying at UCLA. Varien released their first product, named Magento, in 2008 as an open-source platform. The name was inspired by the color magenta, initially featured in their logo. 

 

Today, Magento is the software powering billions of sales. It gives its users complete flexibility and control over the functionalities and design, allowing them to create customized Magento websites. 

 

Of course, you cannot notice too many differences with the first look between the Shopify and Magento platforms. However, they have a lot of dissimilarities when it comes to their features. So, we will start our Magento VS Shopify comparison with: 




The Complexity 

 

One of the most crucial features to consider when choosing an eCommerce platform is its ease to use. Now, both Shopify and Magento platforms are known for their user-friendliness. But which platform is right for you if you are a complete beginner? 

 

Well, Shopify is a total winner in this contest. Remember how Tobias was annoyed with all of the complexities of building an eCommerce platform? That made him come up with a platform that makes the process as simple as it can get. 

 

Shopify is way easier than Magento as it has a drag-and-drop website builder and is a one-stop-shop. This means you can easily customize your website, moving the page elements around as you wish. Shopify does not require a lot of coding from the user, while Magento’s target audience is mainly developers. 

 

So if you are looking for a not-complex, beginner-friendly eCommerce platform, Shopify is the answer. However, if you are a developer and are not scared of a little coding, then Magento should not be a problem. 

 

Still, in this contest, Shopify CMS is the winner. 

 

 

 

 

 

The Look 

 

Although you should not judge from appearance, let's face it: we all want to have a visually stunning website. So yes, you can love at first sight does exist when it comes to websites. But how do you get your Shopify or Magento website to look magical? You need well-designed themes! 

 

That is why our second feature in the Magento VS Shopify contest is the themes. Having the right theme for your website will improve the user experience and help you stand out from the others. So which eCommerce platform is better? Let’s start with Shopify

 

It has a lot of fantastic themes that you can also fully customize according to your needs. And as Shopify is really user-friendly, its themes are pretty easy to use too. So all you need in the case of Shopify is to have your products and content. Anything else can be found in their themes. 

 

Another advantage of Shopify themes is that they are mobile-friendly. Because mobile traffic has increased by 222% in the last few years, having a mobile-friendly theme is almost essential. The only sad news is that although you can find a couple of free Shopify themes, you have to pay for the majority of them. Now, let’s move to Magento

 

First of all, you do not have much choice of themes when it comes to Magento. You have in total 16 themes, and they come with a selection of paid and free options. Only 10 of these themes are mobile responsive: meaning they will allow your Magento site to auto-resize depending on the device.

 

 Though you can implement your theme and update its designs from the backend if you are a developer. This option is only applicable for developers as it requires a lot of coding knowledge. 

 

The great news with Magento is that it is way more flexible and has many customization features available. You can include product sliders to your homepage, add animations, or a newsletter functionality to your website footer. In short, if you are into it, with Magento, you can experiment endlessly and will have far more tools available. 

 

To sum up, if you do not have coding knowledge, then Shopify is the best solution. It has a wide range of themes available and is easily customizable. However, if you are a developer and want to get a more sophisticated look, then choose Magento has a couple of cool features not available in Shopify. 

 

So in this Magento VS Shopify round, there is no clear winner. It really depends on your preferences and coding knowledge. 






 

 

 

The Marketing Features 

 

Any eCommerce owner wants to boost its revenue, so his eCommerce platform should offer the right marketing tools to make it possible. That is why in our Magento vs Shopify comparison, we will include their marketing features too. 

 

As always, we will start with Shopify. Shopify offers a wide range of marketing tools. You can run email campaigns with third-party integrations such as Segundo, Constant Contact, and so on. Shopify allows you to advertise on Facebook, Pinterest, or Instagram directly. Plus, it supports multilingual websites, which means you can target your local market easily. 

 

Magento, on the other hand, uses Marketplace for its marketing tools. That means if you want to run an email campaign, for instance, you need to install the Remarkety extension. And as always, you will need some developer skills to be able to integrate the exceptional marketing tools. In the case of Shopify, the process was easier as it already had built-in marketing tools waiting for you. 

 

So, Shopify is pretty much the winner in this round too. Although Magento also offers a bunch of useful features, Shopify is still simpler to use. Plus, it does not require complicated extensions, as it has most of the tools built into the platform. 



 

 

 

Time for the final verdict! 

 

The winner is: Shopify 

 

In our comparison of Shopify and Magento platforms, we have looked at three major things: the complexity, look, and the marketing tools these platforms offer. In our comparison, Shopify turned out to be the winner as it was pretty easy to use, had a wide range of themes, and buckled you up with marketing tools. However, if you are not afraid of a little coding and want a more sophisticated platform, Magento is the right choice. 

 

Whichever you choose, make sure you also check their forums. Shopify forum provides an enhanced forum experience. You will have access to a community of over 500.000 Shopify merchants and partners and can have meaningful discussions with them. The same goes for Magento. Their forums will help you out in case you have any questions. 

 

So, choose the platform that suits your business needs the most, and scale up your eCommerce!

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.

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.

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!!
