Find person in array

Script Preparation code:
window.bigMap = {}; window.bigArray = Array.from({length: 1000}).map((_, index) => { const id = "person-id-" + index; const person = { id: id, name: `John Doe ${id}`, age: 18 + Math.floor(Math.random() * 70) }; bigMap[id] = person; return person })
Tests:
Find person in map
const id = "person-id-" + Math.floor(Math.random() * 1000); const person = window.bigMap[id];
Find person in array
const id = "person-id-" + Math.floor(Math.random() * 1000); const person = window.bigArray.find(p => p.id === id);
