20 Javascript Projects for Beginners

Are you seeking JavaScript projects for beginners that are fun to build?


If you want to work as a web developer, you should start honing your JavaScript skills right away. You're ready to start your first tiny project after finishing your first tutorial or online course.


After all, if you keep repeating what you already know, you will never achieve your long-term coding objectives. Simultaneously, you want to pick projects that aren't too challenging. Finding a project concept that is just a touch above your current skill level is the key.

However, I understand that it can be challenging to develop JavaScript project ideas that match your talents and are fun to build.


Here is the list of some JavaScript projects that will interest you. Start developing right immediately if you find a project idea that fits your aims and skill level.

1. JavaScript Tic Tac Toe


Another great project idea that you can complete in a single day is creating a simple Tic Tac Toe game with JavaScript.


You'll make a 33-square grid and have two players take turns marking it with cross and circle symbols. The first person wins the game to get three marks in a horizontal, vertical, or diagonal row.


Although the game appears to be simple, you must figure out how to establish the logic that follows the game rules in JavaScript. As a result, before you start writing any code, break down the flow of the game into logical sections.


I find it helpful to design a short flow chart to visualize the potential outcomes of a basic game like Tic Tac Toe. It's easier for me to start creating actual code when I can see the flow on paper.

2. JavaScript Pairs Game


Another interesting project you may do for pleasure (and for your portfolio!) is to code a JavaScript memory matching or pairs game.


The logic is straightforward:


A certain number of cards are face down on the table. The player must locate all of the pairs. You can increase the difficulty by limiting the number of guesses or imposing a time limit on the game's completion.


This is yet another excellent project for honing your JavaScript and HTML and CSS skills.


The most straightforward technique to make matching cards is to use distinct colors that the player must match. However, you can also utilize photos, icons, or numbers.

19. JavaScript Form Validation


Many websites utilize form validation for client-side validation of user details, card data, address details, and other information. If a mandatory input field name exists, the user can type a number, leave the field blank, type only one letter, and so on. All of these validations are simple to implement using JavaScript. 


Let's look at an example of a simple form validation project here.


20. JavaScript Snake Game 


Snake was a popular video game in the late 1970s. The fundamental goal is to avoid touching the walls or the snake's body while navigating a snake and eating as many apples as possible.


The stages we'll take today are as follows:


  • Show the board and a snake that is still.
  • Make the snake move on its own.
  • To modify the snake's direction, use the arrow keys.
  • Score by including food.
  • Final thoughts and resources

What is JavaScript Used For?

Although JavaScript is one of the most widely used programming languages in the world, the question "What is JavaScript used for?" remains a frequently asked one.  


If you have also ever wondered what is the real hype around JavaScript all about then, this article is just right for you. 


JavaScript is a text-based programming language that allows you to construct interactive web pages on both the client and server sides.


Ok, now as you are familiar with the very basic idea of what JavaScript is, let's get right into the depths of its use. 


What is the purpose of JavaScript, and why should you learn it?

What is JavaScript?


Whereas HTML and CSS provide structure and aesthetics to web pages, JavaScript adds interactive components that keep users engaged.


By changing a static web page into an interactive one, including JavaScript, improves the user experience. To summarize, JavaScript adds functionality to web pages.


Menus, animations, video players, interactive maps, and even simple in-browser games may all be readily constructed with JavaScript.


The production of modern web pages is made possible by the collaboration of three languages. These are the following:

  • HTML, or hypertext markup language, is a programming language for putting content on a web page. It supports the addition of text, images, links, and even videos. HTML, for example, allows you to place a login button in a specific location on your website.

  • CSS is a stylesheet language that is used to style HTML content. Using CSS, you can change the shape, size, color, and style of the login button you added with HTML.

  • The subject of this tutorial is JavaScript. Using JavaScript, you can turn standard site items into interactive ones. It works in conjunction with HTML and CSS and is an essential tool for any web developer.


What is JavaScript used for?

Front-End Development


For a front-end web developer, JavaScript is an essential tool. Websites would not have evolved into the dynamic web apps that they are today without it. Image carousels would be a thing of the past. No partial page would retain your position on the page.


Back-End Development


Back-end development is concerned with the parts of a website that are not visible to the user. Server-side development is another term for this.


Databases, APIs, file servers, cloud services, and other back-end development projects are all part of back-end development.


You may now utilize JavaScript for back-end web development as well, thanks to the creation of Node.js, a JavaScript runtime engine. Various JavaScript frameworks have been created to make back-end web development easier. Express Js, Fastify, and Koa are a few examples.


Mobile App Development


The process of building software for a mobile device is known as mobile app development. It entails the creation of applications for mobile platforms.


JavaScript can be used to create mobile apps. JavaScript has been used to create native, cross-platform, and hybrid apps utilizing various Javascript frameworks and tools. Here are a few examples, React Native, NativeScript, Ionic.

Game Development


Games are one of the most enjoyable projects to work on because they may be enjoyed by both you and the end-user.


Depending on the intricacy of the game, there are several ways to create it with JavaScript.


Using HTML, CSS, and vanilla javascript, you can create simple 2D games from scratch. Here's a fantastic resource to get you started:


Ania Kubow teaches JavaScript by creating seven games.

A JavaScript game engine may make the process of creating complicated game concepts, as well as more efficient and faster games, much easier.


Phaser Js, Babylon Js, and Lime Js are examples of these engines.

Add Interaction to Web Pages


Users can interact with web pages using JavaScript. On a web page, there are essentially no restrictions to what you can accomplish using JavaScript - here are a few examples:


  • With a press of a button, you can reveal or hide more information.
  • When the mouse lingers over a button, it changes color.
  • On the site, you can scroll through a carousel of photographs.
  • Zooming in or out on a photograph
  • Using a website to display a timer or countdown
  • Audio and video can be played on a web page.
  • Animations are displayed.
  • Using a hamburger menu with a drop-down menu

Why Use JavaScript?


Let’s take a look at five reasons for how Javascript improves your site and so why you need it.


  • Client-side programming is one of the few languages that does not execute on the web page's server. If you're a web developer, you want the time it takes for a page to load in a viewer's browser to be as short as possible. The user experience suffers as the load time increases. JavaScript animations run on the device processor of the viewer. This greatly minimizes the demand on the webserver and speeds up page loading.

  • JavaScript isn't the only online programming language with a short learning curve. Python, C++, and a few others are among the others. It is, nevertheless, the most popular because it is simple to learn. The syntax used by JavaScript is extremely close to that of English. Developers don't have to spend weeks trying to figure out what each snippet means.

  • Compatibility with other languages: Web servers run in a variety of languages. Python, PHP, Ruby, Rails, ASP.NET, and Java are just a few examples of programming languages.

  • The DOM model is a method of organizing a web page where the elements are styled as "objects" with their own properties. This makes it simple for JavaScript to connect to all of the elements and use them for animations and transitions with minimal problems.

  • Programming without a compiler: Traditional coding requires the use of a compiler. A compiler is used by a browser to convert raw code into understandable syntax.


Sum up 


Although it was created to aid front-end web developers in the construction of interactive features, JavaScript's applications have quickly grown to cover back-end web development, game development, and even mobile app development.


Understanding what JavaScript is used for will help you see the value of learning to code.

Learning JavaScript will increase your employability, provide you the opportunity to start your own business or work as a freelancer, and provide you a lot more job stability.


15 Common Web Developer Interview Questions in 2021

Having extraordinary coding skills is one thing but mastering common web developer interview questions is another story. That is what can help you achieve your career goals, so you should understand the importance of the preparation phase and consider it seriously before applying to the desired company. 


To avoid stress and depression before and after the awaited day, you'll need to prepare thoroughly for the upcoming coding interview. You must be familiar with the interview questions for web developers. This will increase your self-assurance and reduce your tension before the phone or in-person interview.


In this article, we’ll go through the fundamentals of the developer interview process, including the most typical web developer questions you can expect from interviewers and how to answer them in a way that will make them say “WOW.”


Well, let’s get to the point. 15 question you should know well are the following;

General Interview Questions

1. What drew you to the field of coding? 


Alternatively, why do you want to be a software developer?

The majority of interviewers begin with a series of preliminary questions like this. When answering these software engineer interview questions, simply use common sense. Make every effort to be as open as possible. Tell them what drew you to coding in the first place and why you applied for this position.

2. What languages do you work with specifically?


It's that simple. It would help if you concentrated on the languages your web development profession will demand you to use the most. Knowing numerous languages, such as C++, Java, and Python has recently attracted interviewers' interest. So be aware of that when you apply.


3. What has been your coding experience so far?


Because you've presumably recently graduated or completed a coding boot camp or something similar, interviewers won't demand years of experience (and may even skip that question) if you're applying for an entry-level web developer job. However, if you're seeking a position as a senior software engineer, you'll need years of expertise to back up your application.


4. Tell me about your most proud software engineering project. What did you do that was exceptionally successful?


Interviewers are particularly interested in hearing about complex challenges that only a few individuals in the team could solve but which you were able to do yourself. It's crucial to remember not to try to impress the interviewer; it might sound really fake if you do that.

You'll make a desperate impression instead of a nice one. When discussing the problem that no one else has been able to solve except you, be casual. As a result, you’ll project self-assurance and knowledge. It's crucial to be humble when answering this kind of web dev interview questions.


5. Tell me about your least favorite software development project. What would you change if you could?


Learning from your mistakes is an essential skill. Be as open and honest as possible when it comes to admitting past mistakes. Discuss the lessons you've learned so far. Basically, describe how you overcame your greatest obstacles and stood stronger.


Technical Interview Questions


6. Explain AJAX (JavaScript) to me in detail. Can you give me an example of how you've utilized it in the past?


When interviewers ask you “explanatory” questions about software engineering, the goal isn't to explain the definition but to inform them how you'll utilize it in your code. This shows the interviewer that you are capable of “thinking.” It also demonstrates how you approach coding.

The acronym AJAX stands for Asynchronous JavaScript and XML. AJAX is a strategy for using XML, HTML, CSS, and JavaScript to create better, quicker, and more interactive web applications.


7. How do you keep your class modules and assets organized?


Michael Miller, CEO of VPN Online, deserves credit for this. You can write your code in a variety of ways, and all of them are correct. The company you want to work for is likely to have a code writing standard, and your response will be compared to that standard. Typically, most firms seek out engineers who use the simplest method to code and aim to weed out those who prefer a more complex approach. This is because businesses want their code to be simple to maintain and document.

8. What is the distinction between white box and black box testing?


Black box testing is only used to determine whether or not an input is accurate. On the other hand, white box testing examines the function's implementation as well, determining whether it is correct or not.


9. What would you say to non-technical stakeholders about APIs?


It acts as a link between software products. It enables software systems to communicate and synchronize with one another. You can, for example, utilize Facebook's API to show your Facebook posts on your website. Allow visitors to share or comment on your content right from your website, rather than go to Facebook.


10. What's the difference between a non-functional and functional requirement?


A system's type is described by a non-functional requirement (accessibility, maintainability, security). A functional condition, on the other hand, outlines the system's precise capabilities.


11. Could you explain the MVC (model-view-controller) architecture?


It separates the user interface from the data. The MVC design is mostly used for graphical user interface (GUI) applications. The data is stored in the model layer, the information is sent to the user through the display layer, and the controller is the one that makes changes to the model based on user input.


12. Explain big-O notation in the most basic words possible


The big-O notation expresses the speed of an algorithm. This is important regardless of whether you're analyzing other people's algorithms or your own.

The Big-O notation, commonly known as Landau's symbol, describes how a function's runtime or space need increases as the input size grows. This means that the algorithm's speed is measured in the number of operations performed rather than in seconds.


13. What is the definition of a recursive function?


A function that either directly or indirectly calls itself. Instead of running the operation recursively, the recursion continues until it hits a set of parameters that return a value. A recursive function can swiftly handle specific problems.


14. Create a function that calculates the Fibonacci number N.


Geeksforgeeks provided the following code block. It serves as an excellent illustration.


In C++:

//Fibonacci Series using Recursion


using namespace std;

int fib(int n)


if (n <= 1)

return n;

return fib(n-1) + fib(n-2);


int main ()


int n = 9;

cout << fib(n);


return 0;


// This code is written

(Credits to Akanksha Rai)


15. What is the A* algorithm, and how does it work?


It's a pathfinding and graph traversal computer algorithm that's commonly utilized. It uses a heuristic function to calculate the cost of getting from node A to node B. Each step's nodes are grouped in a priority queue.


It adds every node next to the start node into the queue, along with their cost estimates, using the formula f(n) = g(n) + h(n). The actual cost from the start node to node n is g(n), whereas the heuristic function is h(n). The node with the lowest anticipated cost f(n) is enlarged further at each stage. When the final node in a path expands, it is said to be complete.

Sum Up


That concludes this discussion of the most typical software developer interview questions and responses. Whether you're a starter web developer or an experienced software engineer, these interview questions and answers should be valuable to you. You might read the article again to improve your self-assurance even further as you prepare for the interview.


Good Luck!

ATM Interface


Let's switch from games to more serious projects. You certainly are familiar with the functionality of ATMs. There are five main functions you can make with an ATM. 


Withdraw money, make a deposit, check the transactions history, transfer money or quit. Now you can create a project that creates a similar ATM interface and conducts these five functions. 


For your project, you should first ask your user to provide their ID and user pin. If the user provides the details successfully, the menu with the five functionalities pops up. Once your user chooses the option, he unlocks the further functionalities for the specific selection. 


However, consider that the ATM Interface project is a comparatively complicated one and is a console-based application where you should use five different classes. So you might leave it to complete in a stage when you are more comfortable with Java. 


Here is the source code for the ATM Interface project in Java. 


Web Server Management System


Web Server Management System is a project that deals with information management and maintenance. In real life, a similar project is beneficial for active eCommerce websites. 


As a Java programmer, you should find the solution for Web Server Management System by following these steps: 


  • Identify if the consumer is a business entity, an individual user, or another webserver 
  • Identify which is the physical location of the user 
  • Identify the URL authorities and names 
  • Keep the relationships between the company's web services and consumers

You can find the source code for the Web Server Management System here


Airline Reservation System


Another pretty interesting Java project is the Airline Reservation System project. Here you should create a platform that will allow users to: 

  • Reserve and cancel tickets 
  • Automate the functions of the system 
  • Provide quick and automated customer responses 
  • Deal with the routing functions and transaction management 
  • Keep the passenger data

Here is the source code for the Airline Reservation System project. 


Online Book Store


If you are a fan of book stores, especially the online ones, you will love this one. The Online Book Store project is a popular one that aims to simplify the book purchasing process by creating an efficient system that will find the books and identify whether they are available or not. 


You can find the source code for the project here


Snake Game in Java


The Snake Game joins the Brick Breaker and Number Guessing games. It is a 90's game where the purpose is to make the snake eat the tokens without touching the boundaries. The user loses whenever the snake touches the boundary or the screen, and in the end, you should also display the final score. 


You can find the source code for this popular game here


Sum up


As you can see, you don't need to be an advanced Java developer to start working on Java projects. In this blog post, we have mentioned some of the java projects for beginners to start practicing right away. Good luck! 

How Long Does It Take to Learn Coding?

It's almost impossible not to have at least one programmer friend in 2021. If you are not a programmer, then you have at least stared at a seemingly incomprehensible screen of your programmer acquaintance and marveled how he deciphers all that mess! 


Guess what: it might not be that difficult. The truth is, it does not take too much time to learn to program, and in fact, you can become one of those rich geeks too. 


So we are not going to take too much of your time and will jump straight to the main question: 


How long does it take to learn coding? 


If you Google "How long does it take to learn coding ?" the first answer you'll get is from 3 to 6 months. It is because learning coding is a pretty broad term. 


There are programming languages that might take you years to figure out fully and become an expert. At the same time, some of them, like HTML, for instance, require only one to two weeks to learn.


But in general, yes, you can learn programming in 6 months (or even less) and even find a job! If you're one of those who don't believe in such bold statements until they get an example, we got you! 


Clément Mihailescu learned coding only in 6 months and got hired at Google as a software engineer right after that! The best part is that he had zero knowledge or experience in coding before. You can check out his inspiring story here


So yes, in half a year you can learn coding and also find a job. But where should you start? 


3 Ways to Learn to Code


There are different ways you can start your programming journey, but we have singled out the three most popular ones: 


  • Self Learning

If you do not love to be taught by others and learn to program at your own speed, self-learning might be the best solution. 


Self-learning is when you identify your needs, goals and design the study process yourself. This way, you have a lot of freedom and control over your programming studies.


Of course, it requires a lot of self-discipline, but if you are one of those people who know how to self-motivate themselves, then it will work! There are many coding courses and resources out on the Internet, so it will be easy for you to start. 

  • Coding Bootcamps


Coding Bootcamps are fast yet intensive coding courses that prepare teach you how to code. It is how Clément Mihailescu learned to code as a professional in only six months. 


Coding Bootcamps are a good idea if you don't want to get a full degree but still want to go through a more or less traditional teaching system. 


Here you'll have expert teachers that will guide you and help you out and a straightforward studying program that will be already designed for you. The main drawback of these BootCamps is that they are a little expensive. On average, you might expect to pay $13.500 for the program. 


  • Computer Science Degree


Finally, the most popular way to learn to code is to get a computer science degree. Here you will learn the technical aspects of coding and have a more extensive understanding of the industry in general. 


So if you want to immerse yourself in the programming world fully, you might consider getting a degree. But again, there are some drawbacks to this method too: it takes too much time. If you want a full bachelor's degree, you need to spend four years to get it. Master's might take a little less, but it is harder to get accepted there. 


So if you have some 3-4 years to spare, then getting a computer science degree can work. If not, you should choose either of the first two options. 


Here are some tips to help you out to learn to code faster! 


How to learn coding fast


  • Decide what programming language you want to learn


The best way to waste your time is to learn random programming languages very superficially. Yes, we understand it, you are new to programming, and you don't know yet which of the programming languages will suit you the most. 


However, you cannot go on trying all of them one by one. 


Instead, try to figure out what is more interesting for you. For instance, if you want to deal with the aspects of the website or application visible to the user, you should start with front-end languages. 


On the other hand, if you love the technical aspects more, then back-end languages might be the best for you. 


  • Set achievable milestones and goals


Again, don't do everything and nothing at the same time. You need to measure your success somehow. 


For that, set some achievable milestones and goals that you need to reach, and also set deadlines! It will improve your productivity at once and will help you to have some analyzable metrics too. 


Were you able to create a beginner project after the two weeks of your studies? Could you solve a more complex problem in the three months of your studies?  


Create similar questions for you and answer them from time to time to understand your learning stage.


  • Keep practicing


Practice, practice, and practice! If you want to learn to code fast, then coding should be your number one priority. Keep practicing it as much as you can, and you will immediately notice the results! 

Sum up


In the age of technology, it is effortless to learn to code fast and find an excellent job with your knowledge. You might prefer to learn it on your own, attend a Coding Bootcamp or even get a computer science degree. Whatever it is, we assure you that you can learn coding in just a few months if you have your mind to it! 

How to Think Like a Programmer

No matter if you want to become a programmer or not, learning to think like a programmer is a skill that will help you throughout your life. It teaches you the art of problem-solving and makes you a better thinker. So let's jump straight to the main question: 


How to Think Like a Programmer


There is no single answer to the question of how to think like a programmer. But there is a core mentality that all the programmers have: to break the problem down. It will be our starting point in the process of learning to think like a programmer. 


What does it mean to break the problem down? It means to divide the problem into smaller, actionable sections. Think about it this way. Although many people think that computers are smart, the truth is there are unbelievably dumb, and you should explain them every single step. Let's take an example. 


For instance, you want to tell the computer to open the door. If you write "open the door," it will not understand anything and will not know where to start. Instead, you should explain the problem step by step, approximately like this: 


  1. Approach the door
  2. Take the handle with the left hand
  3. Pull it down
  4. Push the door away 


So if you want to think like a programmer and solve problems better, you need to start to break them down into smaller pieces. But how do you solve them? 


 Programmer Mentality: How to Solve Problems


As we said, breaking down the big problem into smaller chunks is your starting point. Next, what you should do is to look at that problem from different angles. Having one interpretation is not enough: come up with a couple of ones. If you need to read the problem multiple times, do so until you feel comfortable with it. 


As you get to the actual code writing, write a pseudo code first. Remember, programming is not only about learning the syntax of the language. It is about knowing how to solve a problem most shortly and efficiently. If you are not coding but still want to learn to think like a programmer, here are some great tips: 

Some Tips to Help you Start Thinking Like a Programmer


1) Start simple 


If the problem you are dealing with is too complicated, try to solve a similar problem that is more simple. You might think it is a waste of time, but in fact, it helps you to remember all the steps you might need to solve the current problem. 


Sometimes when the dilemma has too many riddles, we don't even know where to start. So try to simplify it to the maximum to find a problem that you can solve and then slowly go back to the previous one. 

2) Read it out loud

You should understand the problem thoroughly before you start solving it. Remember we told you to read it a couple of times? Well, another helpful tip could be to read it out loud. You can also try to explain it to one of your friends. It will help you to understand which parts of it are still unclear to you. 


It leads us to the next point: 


3) Collaborate 


Yes, it is fun to find the solution on your own and brag to everyone about how genius you are. But in any good work, collaboration is the key. If you want to grow and learn from others, you need to start working with a team. So, next time if you get stuck on an intricate problem, try to ask for help from your friends. They might introduce you to a new perspective you haven't thought about before. 


It's another thing to talk about problem-solving and different to practice it. To not overload you with purely theoretical information, here are some great websites where you can get your hands on programming problems and have fun at the same time. 


10 Free Coding Challenge Websites

  • TopCoder 

TopCoder is one of the top platforms for finding programming challenges. There are also some competitions from time to time where you can compete with fellow programmers on who finishes the project fastest and in a most efficient way.

Front End vs Back End: What's the Difference?

If you are into programming, you might have heard about front end and back end development. But if you are a complete beginner, these terms might be confusing to you. What exactly do they mean, and what is the difference between the front end and back end? In this blog post, we will take a deeper look at both of them so that you can finally understand which one is more suited for you. 


Let's start from the central question:


Front End VS Back End: What's the Difference?


Front end VS Back end: which one should you choose? Well, to make the right decision, you should first understand what each of them does. 


Here's the difference between front end and back end in one sentence: the front end deals with the stuff the website user sees and interacts with, the back end deals with more technical aspects of website maintenance. 


But, what if someone asked you right now, front end VS back end developer? Still not sure which one you would choose? Well, here's a more profound overview: 


What is the Difference Between Front End and Back End Development?


As a front end developer, you will work on the elements of a website that are visible to the user. But don't confuse it with a web designer. The web designer designs the website and the layout, but the front end developer is the one who implements and builds it. 


The work of the back end developer, on the other hand, is not visible. He is the one who works on the core logic of the website or application. The user still interacts with the components designed by the back-end developer, but indirectly. 


Now let's explore each of them. 

What is Front End Development?

Now let's look at the role of a front end developer from a more technical perspective. How will it be described in the job portals? As a junior front end developer, here's what you can expect to find in an average front end developer job post: 




  • Excellent knowledge of CSS, HTML5, and JavaScript

  • Eagerness to grow and learn new skills

  • Good organizational skills

  • Familiar with web browser testing and able to debug 

  • Passion for web development 

  • Familiarity and understanding of SEO principles 

& more 




  • Create user-friendly and interactive web pages 

  • Maintain and improve the website 

  • Speed optimize the website 

  • Collaborate with the design team 

  • Stay up to date with new technologies 

  • Build and maintain mobile-friendly features 

  • Collaborate with the back end developers

& more 


Above was an example of a job description you might encounter as an entry-level front end developer. To be ready for it, here is what languages and frameworks you should be familiar with: 


Front End Programming Languages




  • HTML is the markup language used to create websites. It stands for Hypertext Markup Language. HTML deals with various aspects of your website. You can use it to create paragraphs, headings, fonts, sections, and other principle features of your web page.


 It is pretty easy to learn, even for a complete beginner. You can learn the basics in a few hours, and two weeks should be more than enough to have a full grasp of the language. 



  • CSS opens up as Cascading Style Sheets. True,  HTML helps you to build the basics of your website. But CSS makes them fancier by defining your website style. It deals with page layouts, fonts, colors, and other similar aspects. 


You can think of it like this: if your website is a house, HTML is its foundation, and CSS is its interior design. Two homes can have the same foundation, but one may have a contemporary, industrial setting, while the other a more bohemian one. 


The same goes for your website. So to come back to more technical terms, you use CSS to describe how your HTML elements get displayed on the website.




  • Finally, the last important language you should know as a front end developer is JavaScript. If you want to spice up your web development game, JavaScript is what you need. It takes your website to a whole new level.


 You can use it to add more complex features such as 2D or 3D animations, interactive maps, scrolling videos, and more. In short, it helps you to make your website more interactive and engaging.


Now let’s jump into: 


Front End Frameworks and Libraries




AngularJS is an open-source framework that is based on JavaScript and is maintained mainly by Google. 




React.js is an open-source JavaScript library. You can use it to build UI components or user interfaces. React.js is maintained by Facebook.  




JQuery is an open-source JavaScript library that simplifies your work by making HTML DOM tree traversal and manipulation, CSS animation, event handling, Ajax, and other things much easier. 




SASS stands for Software as a Service. It refers to cloud-based services, where instead of downloading applications or software, you access it through the web browser. 




Flutter is a UI software development kit, which is created by Google and is open-source. 




Other frameworks that might come in handy are Vue.js, Bootstrap, Laravel, and etc.


What is Back End Development?


Here is what they will require from you as a junior back end developer: 




  • Basic knowledge of front end technologies 

  • Working knowledge of PHP, C++, Java, and other back end programming languages 

  • Good knowledge of SAAS, LESS and other CSS preprocessors

  • Understanding of OWASP security principles 

& more



  • Integrate UI elements designed by front-end developers into the server-side logic 

  • Build and maintain reusable code 

  • Speed optimize the application

  • Build and implement data storage solutions 

  • Take care of the data security and protection 

& more 

Back End Programming Languages


Here is the list of the back end programming languages you need to learn to get a job. 




PHP was designed back in 1994 as a small open source project. However, it was fast to turn into one of the most popular back-end programming languages. PHP is an acronym for PHP: Hypertext Preprocessor. 


It is a server-side scripting language that can be easily embedded in HTML. You should learn PHP to manage databases, session trackings, and similar aspects. You can even build a complete eCommerce website with PHP !



Created by Bjarne Stroustrup C++ was initially an extension to the C programming language. It stands for  "C with Classes."  However, it was also fast to grow throughout the years, becoming a popular object-oriented generic language.


It is used to build games, operating systems, browsers, and so on. C++  is extremely powerful. Some of the large apps like Photoshop, Spotify, YouTube were written in C++.




Java is another general-purpose, object-oriented programming language that is a must for a back end developer. Java is a simple and secure language with many open-source frameworks that is why it is so popular. It is used to develop Java applications in data centers, supercomputers, game consoles, etc. 

Other important languages you will need are: 




A general-purpose, high-level language that is easy to read. 




JS is the world's most popular programming language, which is very easy to learn. 




An open-source and cross-platform JavaScript runtime environment. 


Here is a quick overview of back end frameworks, that will help you: 


Back End Frameworks


We will quickly name the most popular back end frameworks. 


  • Django : the framework for python. Famous use cases include Instagram and Pinterest.

  • Laravel: the framework for PHP. Famous use cases include Deltanet Travel, MyRank

  • Ruby on Rails: the framework for Ruby. Famous use cases include ZenDesk and Shopify.

  • Flask: the framework for python. Famous use cases include Reddit, Red hat. 


& more. 


One more question left unanswered is: 


What is full-stack development?


It's simple: if you are good at both front and back end development, you can become a full-stack developer. So, full-stack development requires a solid knowledge of both front end and back end aspects of web development. 

Sum up


In short, front end development deals with the stuff that the user sees or interacts with, while back end development deals with the server-side logic. And full stack development covers it all. 


So figure out which is the most interesting for you, and start learning!
