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
- More blog posts on ECMAScript.next: ecmascript.next.
- ECMA, TC-39, and Bears - Oh My!
