Benchmark: Small Map vs Small Object.entries iteration

Script Preparation code:

const obj = {
    1: "ASDASDASDASD",
    2: "ASDASDASDASDASDA",
    3: "ASDASDASDASDAAA",
    4: 5242,
    5: "AAAAAA",
    6: "asdasdasdasd",
    7: [24342343, "sweet", "hello"],
    8: [1, 2, 3, 4],
    9: [1, 2, 3, 4, 5],
    10: "AAA",
    11: 5545,
    12: "gutenTag"
}
const map = new Map(Object.entries(obj))

Tests:

Map forEach
let total = 0 map.forEach((k, v) => { total += 1 })
Map for of
let total = 0 for (const [key, val] of map){ total += 1 }
Object.entries for of
let total = 0 for (const [key, val] of Object.entries(obj)){ total += 1 }
