ES6 Feature Proposals

These ES6 feature proposals are not yet final. Read about the Harmony process to learn more about proposal status.

ES6 reached "proposal freeze" in May, 2011: no new major proposals can be added, although proposals can still be removed. TC39 is targeting a release date of December, 2013 for the official ES6 standard, but JS engines are implementing individual features before the spec is finalized.
