About [![Build Status](https://travis-ci.org/mooz/js2-mode.png?branch=master)](https://travis-ci.org/mooz/js2-mode)
======

Improved JavaScript editing mode for GNU Emacs ([description here](http://elpa.gnu.org/packages/js2-mode.html)).

For some of the latest changes, see [latest user-visible changes](https://github.com/mooz/js2-mode/wiki/Latest-user-visible-changes).

Installation
======

The stable versions are hosted at [GNU ELPA](http://elpa.gnu.org/)
(<kbd>M-x list-packages</kbd>).

You can also install the latest development version from
[Melpa](http://melpa.milkbox.net/#installing).

Emacs 22 and 23
===============

This version requires Emacs 24 and `cl-lib` (either built-in or from GNU ELPA above).
For a backward compatible version, check out the branch
[emacs23](https://github.com/mooz/js2-mode/tree/emacs23).

Bugs

Emacs from version 24.2 or earlier?

* Try
[reinstalling or byte-recompiling](https://github.com/mooz/js2-mode/issues/72)
the package.
