New ES6 draft released

# Allen Wirfs-Brock (10 years ago)

The lastest ES6 draft (Rev 33, Feb. 12, 2015) is now available at harmony:specification_drafts#february_12_2015_draft_rev_32 Changes include:

  • Refactoring of module abstract operations to support module loader specifications
  • Additional runtime declaration error checks for non-strict evals (bugs 3410, 3383, 2853)
  • Added early error for super() in non-derived class constructors
  • Added an early error for super property accesses in function/generator declarations/expressions
  • Tweaks to for-in/of grammar to resolve shift/reduce conflict and eliminated an unnecessary look-ahead restriction
  • new and super() expressions can’t be tail calls because they have post return processing
  • Array destructuring stops calling next on its iterator once done state is reached. Only calls return method if iterator isn’t exhausted
  • Function bind now propagates the target function’s [[Prototype]] rather than setting the [[Prototype]] of all bound functions to Function.prototype
  • Resolved bugs: 3843, 3841-3819, 3816-3813, 3811-3810, 3808, 3806-3805, 3793, 3791, 3788-3784, 3782-3760, 3758-3754, 3752, 3745-3738, 3736-3726, 3693, 3687, 3684-3683, 3619, 3607, 3595, 3577, 3575, 3503, 3410, 3383, 2853, 2768, 2606, 2437, 1601
