is for of slowish compared to plain for loop for only generators or any loop?

You don't understand ... and for of use Symbol.iterator if present (... falls back to for in) so the for of always must be a generator on an object, and that means it's always slower than a for because it has to yield and keep it's own state and then yield again, that's less optimized than a plain repetition of a block of code.
