Script Preparation code:

const counter = 10000
const map = new Map()
const array = new Array(counter)

window.counter = counter
window.map = map
window.array = array
for (let i = 0; i < counter; i++) {
    map.set(i)
    array[counter] = i
}

Tests:

Hashmap
for (let i = 0; i < 20000; i++) { window.map.has(500) }
Array.filter
for (let i = 0; i < 20000; i++) { window.array.filter((value) => value === 500) }
