This is a wiki for the ongoing specification work of Ecma TC39, the technical committee tasked with standardization of the ECMAScript programming language. Most of the wiki is world-readable, meaning that anyone can view the pages. Certain sections are restricted to members of the technical committee.

The wiki is running on DokuWiki, a wiki program for editing documentation. It has several features which are helpful for that task. Please take a moment to familiarize yourself with the mechanisms of the wiki.

Please see syntax for a description of the wiki’s markup language. It is very lightweight, similar to plaintext.

The ECMAScript 5th Edition specification has been approved as an Ecma Standard. It can be accessed here: http://www.ecma-international.org/publications/standards/Ecma-262.htm

DokuWiki permits organization of pages into subdirectories (or “namespaces”). I have added a few namespaces to help organize our work. Anyone can add new namespaces, just like anyone can add new pages, but it helps if we keep the number few so that we can find one another’s work.

• The 'strawman' namespace is intended to hold Harmony proposals prior to approval.
• The 'harmony' namespace is intended to hold proposals on the “ES-Harmony” language.
• The 'meetings:' namespace is for posting meeting agendas, minutes, schedules, etc.
• The 'resources:' namespace is for uploading papers or listing pointers to external sites of interest to the work of this group.
• The 'es3.1:' namespace was for the “maintenance of es3” work, which became ES5.
• The 'ses:' namespace is for the Secure ECMAScript work.
• The 'conventions:' namespace is for patterns and snippets of code offered as an agreed compromise to unify existing diverse practices.

Known obsolete:

• The 'feature specs:' namespace is intended to hold detailed feature definitions.
• The 'proposals:' namespace is intended for informal discussion of proposed changes.
• The 'discussion:' namespace is intended for permanent archival of discussion.
• The 'clarification:' namespace is intended to capture high-level issues that need clarification.
• The 'bugs:' namespace is for tracking the status of bugs in the spec document
• The 'ri:' namespace is for information about the reference implementation that’s not in the mtn
• The 'spec:' namespace is intended to hold actual proposed and agreed-to chapter text for the final ES4 spec document
