Script Preparation code:

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

Tests:

for 3
'use strict'; var l = arr.length; var result=0; for (var i = 0; i < l; i++) { result += arr[i] * 5; }
for 4
'use strict'; var result=0; for (var i = 0; i < arr.length; i++) { result += arr[i] * 5; }
copy
'use strict'; var arr = []; for (var i = 0; i < 1000; i++) { arr[i] = i; } var result=0; for (var i = 0; i < arr.length; i++) { result += arr[i] * 5; }
