In C, this loop would get unrolled to a no-op in a release environment. Source: https://godbolt.org/z/1sb5Tb3xv https://godbolt.org/z/1sb5Tb3xv

  I used an empty loop just to simplify an example. Obviousy in real code the loop would do domething useful and wouldn't be optimized out.

    But if your loop is busy doing stuff that’s hundreds of bytecode ops long, is worrying about the few extra bytecode ops that a for loop takes worth it?

      It's not like those hundreds of bytecode ops aren't slow as molasses too, for similar reasons.

      How else would they feel superior to someone else, if not by comparing Python/JS to C's speed all the while talking about applications where C is never going to be used?
