I hope this is the case, otherwise someone somewhere thought this was the best JS code to solve the problem:

for (i = _i = _ref = this.length - 1; _ref <= 1 ? _i <= 1 : _i >= 1; i = _ref <= 1 ? ++_i : --_i) {

I would guess this is JS transpiled from CoffeeScript or something similar. That makes it an even less fair comparison, as ClojureScript would compile down to something just as wacky looking.
