ECMAScript.next features are taking shape

The ECMAScript wiki has two pages with features that might make it into ECMAScript.next:
  • Harmony proposals: Features that browser vendors (in the TC39 [2]) agreed should be part of ECMAScript.next. Highlights:
    • Destructuring assignment
    • Iterators
    • Generators
    • Modules
  • Strawman: Proposals where TC39 is still debating whether to include them in ECMAScript.next or not. Quoting a tweet by Brendan Eich:
    See [the Strawman page] for “not yet Harmony but maybe ES.next.next”. A few of these should still make ES.next...
    Examples:
    • Shorter function syntax
    • Data structures: maps, sets, ...
    • Class abstractions
    • Paren-free syntax
