Benchmark: Array for vs Array for of vs Set for of vs Map for of

HTML Preparation code:

<div id='test'></div>

Script Preparation code:

function fn() {}
var arr = new Array(100).fill(0).map((x, i) => i.toString());
var set = new Set(arr);
var map = new Map(arr.map((x, i) => [i, x]));

Tests:

Array for-loop
var t = 0; for(i=0, l = arr.length; i<l; i++){ t = arr[i] }
Array for..of
var t = 0; for (let value of arr) { t = value; }
Set for of
var t = 0; for (let value of set) { t = value; }
Map for of
var t = 0; for (let [key, value] of map) { t = value; }
