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

it's an interesting thought, but if you dislike the syntax for the loop, you could always do a different type of loop:

var i = arr.length; 
while (i--) {
    // do stuff
}

the reverse while loop is generally faster than a for loop as well.
