Yeah, this is rad, as I imagine there&#x27;s some overhead to running the transpiled babel ES6 code compared to running the native ES6 features. At least some things may be faster - I remember lexical block scoping (let and fat arrow) causing perf issues in traceur.<p>Now I just need to be able to rely on these features being present in the browser so I can just write native ES6 everywhere and skip that build step entirely.
