Benchmark: Arary iteration comparison

Script Preparation code:

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

Tests:

for-native
var newArr = []; for (var i = 0, len = arr.length; i < len; i++) { newArr.push(someFn(arr[i])); }
for-with-init
var newArr = new Array(arr.length); for (var i = 0, len = arr.length; i < len; i++) { newArr.push(someFn(arr[i])); }
for..of-native
var newArr = []; for (const el of arr) newArr.push(someFn(el));
for..of-with-init
var newArr = new Array(arr.length); for (const el of arr) newArr.push(someFn(el));
map
var newArr = arr.map(someFn)
