JavaScript for-loop alternative: repeat(n, function(i) { … });

Question

This is the regular for-loop:

for (var i = 0; i < n; i++) { ... }

It is used to iterate over arrays, but also to just repeat some process

Answer 1

Besides what you have already stated the main downside I see is that a "return" statement will work differently. (Which is often why I end up using "for" over "$.each" many times in my own ventures.)
