Benchmark: create new Map vs create new Array

Tests:

new Array
let arr = [1,2,3,5,6,7,8,9,10,11,12,13] const filteredArr = arr.filter(item => item !== 1) const result = arr.find(item => item === 13) arr = filteredArr
new Map
const map = new Map([['1', '1'], ['2', '2'], ['3', '3'], ['4', '4'], ['5', '5'], ['6', '6'], ['7', '7'] ,['8', '8'] ,['9', '9']]) map.delete('2') const result = map.get('1') const updatedMap = new Map(map)
