Benchmark: Array.find() vs for loop

Script Preparation code:

const arr = Array.from({ length: 20000 }, (_, i) => ({ property: i }))
const elementToFind = 15000;

Tests:

Array.find
const arr = Array.from({ length: 20000 }, (_, i) => ({ property: i })) const elementToFind = 15000; const element = arr.find((el) => el.property === elementToFind);
For-loop
const arr = Array.from({ length: 20000 }, (_, i) => ({ property: i })) const elementToFind = 15000; let element = undefined; for (let i = 0; i < arr.length; i++) { if (arr[i].property === elementToFind) { element = arr[i]; break; } }
