Script Preparation code:
const object = (id) => ({ a: () => id, b: "id-" + id, }); const map = new Map(); const arr = []; const max = 100; for (let i = 0; i < max; i++) { map.set(i, object(i)); arr.push({ id: i, ...object(i) }); } const rng = () => Math.floor(Math.random() * max);
Tests:
Array.findIndex
const id = rng(); const index = arr.findIndex((obj) => obj.id === id);
Map.get
const id = rng(); const value = map.get(id);
