for (let i = 0; i < 1000000; i++) {
  data.add(i)
}
window.data = data

Tests:

forEach
let sum = 0 window.data.forEach((v) => { sum += v }) console.log(sum)
values
let sum = 0 const itr = window.data.values() let res = itr.next() while (!res.done) { sum += res.value res = itr.next() } console.log(sum)
for loop
let sum = 0 for (const v of window.data) { sum += v } console.log(sum)
