Benchmark: Array loop vs foreach vs map vs while (fixed v2)

Script Preparation code:

var arr = [];
let result = 0;

for (var i = 0; i < 1000000; i++) {
    arr[i] = i;
}

function someFn(i) {
    result = i + 1;
    return result;
}

function fixResult() {
  console.log(result);
}

Tests:

forEach
arr.forEach(function (item){ someFn(item); }) fixResult();
for
for (var i = 0, len = arr.length; i < len; i++) { someFn(arr[i]); } fixResult();
map
arr.map(item => someFn(item)) fixResult();
while
let i = 0, len = arr.length; while (i<len) { someFn(arr[i]); i++; } fixResult();
