V8 Release 5.1
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.Including but not limited to: Proper tail recursion (^_^) and destructuring.Tracked at http://node.greenWe don't have an ES2015 features page up to date yet, but it's going to be ready any day now (and we're going to link to node.green anyway most likely).
