How does native ES6 performance compare with the performance of ES6 compiled into ES5?<p>Because right now there isn&#x27;t enough cross-browser ES6 support to be able to use it reliably with compilation; given that the compilation procedure is easy and relatively pain-free (at least until you see the horrifying code that Babel produces when you ask it to transpile generators), I&#x27;m wondering how much of an issue ES6 performance is in the real world.
