To some extent because parts of the spec aren't yet stable enough, but mostly because implementing all new features is a huge amount of work. Substantial parts of the spec are, however, implemented in various engines. A good overview of the current state can be seen here: http://kangax.github.io/es5-compat-table/es6/ Additionally, there are a few transpilers that transform ES6 code (again, not with all features supported) to ES5 as supported in pretty much all browsers nowadays. Traceur, one of those, is in the table I linked to above. hth, till ___ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss

ES6 draft Rev24 now available
At
http://wiki.ecmascript.org/doku.php?id=harmony:specification_drafts#april_27_2014_draft_rev_24
Changes include:
• Several important bug fixes to Function Declaration Instantiation
• Updated RegExp so that subclasses that over-ride exec semantics don’t
have to also over-ride match/replace/search
• disallowed a line break between ArrowParameters and the ⇒
• Adjust Array.prototype.reverse and Array.prototype.unshift to
eliminate several unnecessary MOP calls that were exposed if the array is a
proxy
• Object.assign now accepts multiple source arguments
• arguments object now have an @@iterator own property
• %TypedArray% constructors now processes iterables as an argument.
• Changed length property value of Symbol, Map, Set, WeakSet, WeakMap
to 1 to be consistent with most other built-in constructors
• Added Annex B item about var declarations in catch clauses that
binding the same name as a catch parameter
• Array.from/typedArray.from now calls filter function with two
arguments.
• Eliminated static semantic rules that made the following an early
error function({x}){var x} or generator(x) {var x}. A var declaration now can
always be the same name as a formal parameter
• Made for (let x in x), etc. a TDZ violation
• further tweaking of super related productions in MemberExpression and
NewExpression
• Bug fix in GetBindingValue to make TDZ work. Accessing an
uninitialized binding always throws and is not conditional on strict mode.
• Started update of Annex A. Lexical grammar updated
• Resolved bugs: 2729, 2727, 2724-2722, 2714-2713, 2711-2706,
2695-2688, 2685, 2681-2660, 2658-2657, 2655-2654, 2652-2649, 2647-2640,
