Benchmark: Array vs Map vs object iteration 3

Script Preparation code:

var a = []
var m = new Map()
var o = {}
for (var i = 0; i < 2000; i++) {
    a[i] = i;
    m.set(i.toString(), i);
    o[i.toString()] = i;
}
var results = []

Tests:

Array.forEach
a.forEach(i => { results.push(i * 2) })
Array for...of
for (const i of a) { results.push(i * 2) }
Map.forEach
m.forEach(i => { results.push(i * 2) })
object for...in
for (const i in o) { results.push(o[i] * 2) }
