const genRandArr = () => Array.from({ length: 1e7 }).map(() => Math.random());
var arr = genRandArr();
var set = new Set(genRandArr());

Tests:

Array iteration
let sum = 0; for (const el of arr) sum += el; console.log('Array result: ', sum);
Set iteration
let sum = 0; for (const el of set) sum += el; console.log('Set result: ', sum);
