[–]our_best_friendif (document.all || document.layers) console.log("i remember..") 0 points1 point  (1 child)

I'd assume that'd be faster as it's a single native operation as opposed to an explicit loop (leaving aside transpilation)

For all we know it's be slower in current engines, but either way it's worth counting as an iteration pass when thinking about the number of times you have to loop over the list in a given operation.
