Why Should I Learn JavaScript in 2023

To become a web developer in 2023 JS is a must have skill. Similarly, if you want to hire Js developers then you should definitely know JavaScript. The beginners are okay with having JavaScript knowledge but for a JavaScript developer for hire, in a mid a or senior position, they should be a JS master. 

Today we will explore why JavaScript is important? Why should you learn? And is it even worth learning in 2023? But before going further, know that if you want to hire JavaScript programmer then stop reading further and hire JavaScript developer today from vteams.

Without any further ado let’s get to it! 

What is JS actually?

JS, a.k.a, JavaScript is an OOP based programming language. It helps making websites and web apps interactive and responsive. HTML and CSS are the bare bones of any website, but with only that websites do not have any functionality or features. JS adds elements like dropdown, contact forms, modals and so much more. 

These days, about 98% of websites use JavaScript. With JS you can develop a complete website, meaning front-end and back-end. Apart from websites it can be used to build browser games, mobile apps, server apps etc.

So should I learn JavaScript in 2023?

The short answer is yes. Even if you are a beginner and you might switch roles from web developer to something else, like mobile app developer, you should still learn JS. Because it will help you, as it is everywhere on the web. Even when changing languages you would have mastered the basics so moving to another language means just learning the syntax and you are good to start development.

Let’s look at the benefits.

Why learn JavaScript?

Obviously, if you want to become a web developer then learning JavaScript is a must. If you have set your heart on learning JavaScript then let’s have a look at a few reasons why you should start learning it. 


It is a versatile programming language with which you can shift to frontend development, backend development, full stack web developer, or mobile app developer.

To become a frontend engineer you have to master JS and one of its frameworks like React or Angular. Conversely, if you want to become a backend engineer you have to learn Node.js and databases. To become a full stack developer you need both front-end and back-end skills. On the other side of the spectrum, you can learn React Native, which is also a JavaScript framework to develop native mobile applications.


According to this report more than 70% companies actively look for JavaScript programmers for hire. If you search to hire JS developers or JavaScript developer jobs hundreds and thousands of jobs will pop up. Meaning there is a huge market and demand for JS developers. 


JavaScript is easy to learn, even for novice and people with non-technical backgrounds. Without having to set up a development environment you can simply install a code editor and start development. 

The instant feedback with development is also something that pumps programmers to experiment with programming. 

JavaScript learned with JS can be transferred to other languages so learning it is beneficial in any way. If you are looking to hire JavaScript programmer then vteams is the best place. Contact their professionals today to know more.

How To Test JavaScript Code

One of the biggest mistakes developers make is deploying the code without testing it beforehand. This undermines the quality of your product and erodes customers’ faith in you, doing more harm than you might realize to your company. JavaScript code testing is now simple thanks to a variety of tools. Whether you are a JavaScript developer or looking to employ a JavaScript programmer, this post is for you.

Two key methods for evaluating code and enhancing both its quality and the security of your software are unit testing and functional testing. The reasons for and methods for testing your JavaScript code are covered below.

Why is Testing Important?

The foundation of any software build is testing. You can either test your JavaScript code in the browser or you might need to utilize other methods, depending on the framework, additional tools, and the kind of programme you are producing.

However, because JavaScript is a loosely typed language, debugging in a browser or locally becomes quite challenging. So selecting a tool becomes necessary.

Type of Tests

Unit Testing
When you unit test your software, you test one piece of it at a time. It works similarly to “split and conquer.” For instance, unit testing would include testing each class individually if your software contained distinct classes that each carried out certain functions. The code can also be separated into frontend and backend components.

Test of Integration
Integration testing is primarily concerned with how various components interact with one another while the tests are run. While individual modules may perform flawlessly, when they are combined and interact with other modules, the functionality may be broken. Therefore, integration testing is employed to verify that the software will function as intended after being assembled.

Complete Test
E2E testing is another name for end-to-end testing. This comes after integration and unit testing. You test the entire programme at this point by entering commands that actual users could type. Typically, it is accomplished by automation using either specialized tools or scripts.

Beta Testing or User Testing
Beta testing is another name for user testing. Most software development firms or freelance developers don’t do this. However, in this phase, you provide a select group of users permission to use your app for a while. You modify the software as necessary based on their input.

The Testing Equipment Available

The browser-based language JavaScript is used. It is therefore simpler to test in the browser. Developers can choose the tool that best matches their needs from a wide variety of tools available for testing JavaScript code in browsers. Several well-known tools for testing JS code in the browser are listed below:

  • codedamn
  • JSFiddle
  • JS Bin
  • JavaScript Playground
  • Google Chrome + VSCode
  • Liveweave
  • JSPen
