Script Preparation code:

   var arr = [];
    for (var i = 0; i < 1000; i++) {
      arr[i] = i;
    }
  
    function someFn(i) {
      return i * 3 * 8;
    }

Tests:

foreach
arr.forEach(function (item){ console.log(someFn(item)); })
for
for (var i = 0, len = arr.length; i < len; i++) { console.log(someFn(arr[i])); }
map
arr.map(item => console.log(someFn(item)))
for no fn call
for (var i = 0, len = arr.length; i < len; i++) { console.log(i * 3 * 8); }
