Benchmark: Array/Set/Map/Object Iteration 2

Script Preparation code:

var obj = {"one": true, "two": true, "three": true, "four": true, "five": true, "six": true, "seven": true, "eight": true, "nine": true, "ten": true};
var map = new Map([["one", true], ["two", true], ["three", true], ["four", true], ["five", true], ["six", true], ["seven", true], ["eight", true], ["nine", true], ["ten", true]]);

var arr = ["one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"];
var set = new Set(["one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"]);

Tests:

Object Iteration
for (const key in obj) { void(obj[key]); }
Array Iteration
for (const element of arr) { void(element); }
Map Iteration
for (const element of map) { void(element); }
Map Iteration (keys)
for (const element of map.keys()) { void(element); }
Map Iteration (values)
for (const element of map.values()) { void(element); }
Set Iteration
for (const element of set) { void(element); }
Map Iteration for
for (let i=0; i<map.size; i++) { void(map.get(i)); }
