Best JavaScript IDEs and Code Editors To Use In 2021

javascript IDE

JavaScript… Heard a lot about this name? If you are a programmer or web developer, then I am sure, you know the value and usefulness of JavaScript. It is one of the most popular and one of the most used programming languages in the world. Being one of the three pillars of front-end web development along with HTML & CSS, JavaScript has gone through some major updates since its inception. Thanks to all the hard work done by its creators, now it supports several frameworks that allow developers to use it as a full-stack language for back-end and GUI games as well.

Though this programming language was created for the web, there are a lot of things that you can do with this language. Such as, you can program a flying robot, create web-based slides, server applications, web servers, apps for smartwatches or mobile applications, digital art projects, games and so much more. This is mainly because all or most of the current web browsers understand JavaScript.

Its overall popularity and use have led to a significant surge in the development of IDEs and code editors. But before checking out the top IDEs or code editors, let’s first understand the difference between these two.

IDE or Integrated Development Environment is a complete software that allows you to write the code. It provides you tons of extra features that also allow any programmer to edit, modify, execute, run, debug, or deploy your code. IDE also comes with auto code completion which is very efficient making you more productive.

Contrary to this, Code Editors are the more lighter versions with respectively fewer features. Both IDE & editors have their own sets of advantages. Nonetheless, in recent times, the difference between both of them has been a little blurred, thanks to all the modern advancements.

There are numerous JavaScript IDE & editors currently present on the internet, and each of them has its own sets of pros and cons. Some of these JavaScript IDEs are free and some are paid too. If you ever had a confusion to choose the right IDE or editors, then here’s the article which will discuss the top 15 development tools for JavaScript.
