There are many tools that let you write code online. Some are free, some are paid. The best Javascript IDE can be overwhelming to choose among them.
To help you make an informed decision about the IDE you should use, here is an overview of the top 5 free and affordable JavaScript IDEs of 2020.
Visual Studio Code

Probably the biggest player right now in the code editor space, Visual Studio Code is open source, developed by Microsoft (and, of course, all of its open-source contributors).
Despite its name, it’s quite different from Visual Studio (Microsoft’s premium editor, primarily aimed at .NET development). It’s very flexible and works with most, if not all, popular programming languages.
There are also plenty of extensions available to download for free, which extend its functionality even further. You can even write your own and since it uses web technology, it’s all just JavaScript.
It also integrates well with Visual Studio Code Online. This is a service hosted by Microsoft that lets you run Visual Studio Code on a server, which can do all the heavy lifting for you.
Microsoft also offers a service called Live Share, which lets you invite another developer to work on your project with you remotely. You can see each other’s cursors and edit the same files at the same time.
