js2-mode is an improved JavaScript major mode for GNU Emacs featuring a full JavaScript parser (AST) for accurate syntax highlighting and editing. It integrates with Emacs' built-in js-mode for indentation and supports JSX via companion modes.
Use cases
- edit JavaScript files in Emacs with better syntax highlighting
- get a JavaScript AST in Emacs for refactoring tools
- indent and highlight JSX/React code in Emacs
- replace the default js-mode with a parser-based JavaScript mode
When to choose
- you use GNU Emacs 24.1+ and want robust JavaScript editing
- you need an AST-based JS mode to power tools like js2-refactor or skewer-mode
When to avoid
- you are on Emacs 27+ and only need highlighting/indentation, since built-in js-mode covers that
- you need full IDE features like LSP-driven completion and diagnostics
