Nit regarding proper tail calls versus tail call optimization: As I understand, JS maybe will be getting the former but not necessarily the latter. I.e., you'd avoid blowing the call stack, but not necessarily get a dramatic speed boost just for moving something to tail position.

I thought "optimization" in tail call optimization refers to optimizing memory usage--eagerly discard or reuse the frame upon a tail call.

  There's also speed gains to be had from re-using frames instead of creating new ones in some languages, but this is a fair point.
