* Description
This layer adds support for the JavaScript language using [[https://github.com/mooz/js2-mode][js2-mode]].
** Features:
- Smart code folding
- Refactoring: done using [[https://github.com/magnars/js2-refactor.el][js2-refactor]].
- Auto-completion and documentation: provided by [[http://ternjs.net/][tern]]
- CoffeeScript support
- Formatting with [[https://github.com/yasuyk/web-beautify][web-beautify]]
* Install
To use this contribution add it to your =~/.spacemacs=
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(javascript))
#+END_SRC
You will also need to install =tern= to use the auto-completion and
documentation features:
#+BEGIN_SRC sh
$ npm install -g tern
#+END_SRC
To use the formatting features, install =js-beautify=:
#+BEGIN_SRC sh
$ npm install -g js-beautify
#+END_SRC

| ~SPC m r a o~ | replaces arguments to a function call with an object literal of named arguments |
| ~SPC m r b a~ | moves the last child out of current function, if-statement, for-loop or while-loop |
| ~SPC m r c a~ | converts a multiline array to one line |
| ~SPC m r c o~ | converts a multiline object literal to one line |
| ~SPC m r c u~ | converts a multiline function to one line (expecting semicolons as statement delimiters) |
| ~SPC m r e a~ | converts a one line array to multiline |
| ~SPC m r e f~ | extracts the marked expressions into a new named function |
| ~SPC m r e m~ | extracts the marked expressions out into a new method in an object literal |
| ~SPC m r e o~ | converts a one line object literal to multiline |
| ~SPC m r e u~ | converts a one line function to multiline (expecting semicolons as statement delimiters) |
| ~SPC m r e v~ | takes a marked expression and replaces it with a var |

| ~SPC m r s l~ | moves the next statement into current function, if-statement, for-loop, while-loop |
| ~SPC m r s s~ | splits a =String= |
| ~SPC m r s v~ | splits a =var= with multiple vars declared into several =var= statements |
| ~SPC m r t f~ | toggle between function declaration and function expression |
