Structure of the MDN JavaScript docs
All reference pages should have a consistent structure with information about browser compatibility, specification status, examples, introduction texts, proper tagging and formatting (content hierarchies, no links to redirects). Integrating the quicklinks navigation is also part of this update. Going through these pages can then help to identify gaps in our reference material and find pages in need of further updating for ES 5.1 and 6.

Other tasks to do
- asm.js explanation doc ?
- Go through Firefox release notes for developers and site compat notes and make sure JS changes are documented properly in the references.
- Make sure our compat tables are up to date by also going trough bug trackers of other open source browsers (e.g. WebKit, Blink)
- Write a changelog for Chrome JavaScript releases like we have for Firefox. Same for other browsers/node.js?
- Meta article about how to document in the JS MDN area.
- Create a page that explains error messages (v8). So that people searching for errors will find guidance.
Tagging standard
- For all pages at least the tag "JavaScript" should be added.
- For methods belonging to an object it the name of the Object should be added (e.g.
String.fromCharCodeshould have "String"). - Methods should have "Method" and properties need a "Property" tag. All prototype methods have the "prototype" tag.
- Features added in a new ECMAScript version have a "ECMAScript6" plus "Experimental".
- Deprecated and obsolete features have the same named tags.
- If pages need any type of work, a "Need*" tag should be added (see above).
Specifications
The following specifications are taken under consideration for this project:
| Specification | Status |
|---|---|
| ECMAScript 5.1 (ECMA-262) | Standard |
| ECMAScript 2015 (6th Edition, ECMA-262) | Standard |
| ECMAScript Internationalization API 1.0 (ECMA-402) | Standard |
| ECMAScript Internationalization API 2.0 (ECMA-402) | Standard |
