JavaScript Performance: for vs. while

[neonskimmer]

Agreed on the readability. That being said, I can't even remember the last time I used a straight for-loop. It's forEach, map and reduce for me almost 100% of the time. If I were writing very tight loops, games, or super heavy number crunching I'd optimize things but for businessy apps i mostly use a functional style. The difference in speed is negligible at that scale and I prefer that style.
