12 Best Online JavaScript Translators for Coding Anywhere, Anytime

JavaScript is one of the most popular and widely used programming languages. Its flexibility and strength are some of the reasons for its popularity. It has a framework that can also be used on the server and client side which explains why its popularity is growing.

Developers need a variety of tools to build and run a JavaScript application. JavaScript compilers are one of the important tools that experienced programmers, students, and programming enthusiasts use to write and test code.

In this article, we’ll define what a JavaScript compiler is, why you should use one, and review some of the best:

What is a JavaScript compiler?

JavaScript is a high-level programming language, and its code in pure format cannot be read by computers.

A JavaScript compiler is a tool that converts JavaScript source code into machine-readable code before running the program.

A compiler changes/compiles this high-level language into binary files that computers can read.

Why use a JavaScript compiler?

You can use the integrated development environment or the code editor to write, run, and test your code. Alternatively, you can avoid these two and use an online JavaScript compiler.

Here are some reasons why you might settle for the latter;

  • Seamless execution: You don’t need to download JavaScript and related packages to compile and execute your code. The online compiler takes care of everything.
  • Increased productivity: You don’t have to switch between programs to compile and execute your code. To work on JavaScript code, all you need is a web interpreter window.
  • No need to stress your machine: JavaScript compilers are mostly found in optimized environments. You no longer have to stress your CPU when running code locally.
  • Simple: some IDEs and code editors can sometimes have a lot of features you don’t need. JavaScript Online is simple and has just enough features to get the job done.
