Benchmark: Array of Values from Map vs object types

Script Preparation code:

var mapCase = new Map([
    [1, "one"],
    [2, "two"],
    [3, "three"],
    ["four", 4],
    ["five", 5],
    ["six", { hello: "world" }]
]);
var objCase = {
    1: "one",
    2: "two",
    3: "three",
    "four": 4,
    "five": 5,
    "six": { hello: "world" },
}

Tests:

Array.from Map values
var arr = Array.from(mapCase.values())
Spread Map values
var arr = [...mapCase.values()]
Object.values object
var arr = Object.values(objCase)
