In case anyone is wondering, NodeJS v6 is right around the corner with V8 5.x. Node is going to get a serious boost of ES2015 features.<p>Including but not limited to: Proper tail recursion (^_^) and destructuring.<p>Tracked at <a href="http:&#x2F;&#x2F;node.green" rel="nofollow">http:&#x2F;&#x2F;node.green</a><p>We don&#x27;t have an ES2015 features page up to date yet, but it&#x27;s going to be ready any day now (and we&#x27;re going to link to node.green anyway most likely).
