Benchmark: Recreate Object vs Map vs Array vs Set

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:

Create Object
var obj1 = {...obj};
Create Map
var map1 = new Map(map);
Create Array
var arr1 = [...arr];
Create Set
var set1 = new Set(set);
