Nope. Loops are unnecessary unless you have mutation. If you don't mutate, there's no need to run the same code again: if the state of the world did not chang

Nope. Loops are unnecessary unless you have mutation. If you don't mutate, there's no need to run the same code again: if the state of the world did not change during iteration 1, and you run the same code on it again, the state of the world won't change during iteration 2.
