Script Preparation code:

const data = new Set
for (let i = 0; i < 1000000; i++) {
  data.add(i)
}
let sum = 0
function forEach(v) {
sum+=v
}

Tests:

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