Proposals [0] that made it into ES8 (“what’s new”):

* Object.values/Object.entries - https://github.com/tc39/proposal-object-values-entries

* String padding - https://github.com/tc39/proposal-string-pad-start-end

* Object.getOwnPropertyDescriptors - https://github.com/ljharb/proposal-object-getownpropertydesc...

* Trailing commas - https://github.com/tc39/proposal-trailing-function-commas

* Async functions - https://github.com/tc39/ecmascript-asyncawait

* Shared memory and atomics - https://github.com/tc39/ecmascript_sharedmem

The first five have been available via Babel and/or polyfills for ~18 months or so, so they’ve been used for a while now.
