async&#x2F;await isn&#x27;t part of any standard yet. It&#x27;s a stage 3 proposal at this time, which means it may not even land in ES 2016: <a href="https:&#x2F;&#x2F;github.com&#x2F;tc39&#x2F;ecma262" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tc39&#x2F;ecma262</a><p>The last thing we want is native support for pre-standard features. As long as it&#x27;s not in a spec (or draft at least), it&#x27;s sci-fi.<p>Besides, node doesn&#x27;t implement language features, V8 does.
