What to look for in JavaScript Editors

Strong ES2015+ support

It should offer strong support for latest JavaScript features.

Most editors do so today but keep in mind the larger your editor is, the slower it will typical be to add support for new JavaScript features.

It will also likely to be slower to add support for alternative languages that transpile to JavaScript in future.

Features to look for:

  • Autocompletion
  • Parse ES6 imports
  • Report unused imports
  • Automated refactoring

Many editors now offers build in support for popular frameworks and libraries like Angular, Node, React, etc.

Built in terminal

Tools like WebStorm provides build in terminal. Most of the tools in JavaScript rely on the command line. So it would be good to have it.

Some editors like Atom, allow adding a built-in terminal by installing  a plugin.

Some of the best free editors are:
