Script Preparation code:

var arr = [];
  for (var i = 0; i < 1000; i++) {
    arr[i] = i;
  }

  function someFn(ix) {
    return ix * 5;
  }

Tests:

while
var l = arr.length; while(l--) { someFn(arr[l]); }
for
for (var i = 0; i < arr.length; i++) { someFn(arr[i]); }
for 2
var l = arr.length; for (var i = 0; i < l; i++) { someFn(arr[i]); }
for 3
var l = arr.length; var result=0; for (var i = 0; i < l; i++) { result += arr[i] * 5; }
for 4
var result=0; for (var i = 0; i < arr.length; i++) { result += arr[i] * 5; }
