Good question. People will say blanket things like "for loops are always faster", but it -really- depends on every individual use case. So you might want to create solutions for each to the best of your ability, then benchmark them.

Here are a couple of the top solutions (one for switch statement, and one for for loops) benchmarked against each other: https://jsbench.me/e3lh84u45z/1

It seems like the switch statement solution is 11% faster, but you'll notice the for loop example has some regex bloat in there which is probably slowing it down.

Create your own clean solutions and benchmark them yourself. It's kinda fun.

Can you guys start running these descriptions through GPT-4 or something so they are semi-legible? Half these katas have descriptions like "If eat goes 4 down then art was do less than Tom saids leak."

I feel like I'm having a stroke.

This is the only acceptable solution.
