Benchmark: map Vs object vs array

Script Preparation code:

const map1 = new Map();
map1.set('a1', 1);
map1.set('b1', 2);
map1.set('c1', 3);
map1.set('d1', 4);
map1.set('a', 5);
const map2 = new Map();
map2.set('a2', 1);
map2.set('b2', 2);
map2.set('c2', 3);
map2.set('d2', 4);
map2.set('a', 5);

const obj1 = {
    'a1': 1,
    'b1': 2,
    'c1': 3,
    'd1': 4
};
const obj2 = {
    'a2': 1,
    'b2': 2,
    'c2': 3,
    'd2': 4
};

const arr1 = [1, 2, 3, 4];
const arr2 = [5, 6, 7, 8];

Tests:

map test for merge
[...map1.values(), ...map2.values(),]
map.values()
map1.values();
object merge
[...Object.values(obj1), ...Object.values(obj2),]
object values
Object.values(obj1)
array merge
[...arr1, ...arr2,]
