Benchmark: Generator function vs array loop vs map

Tests:

generator
const array = [...Array(10000).keys()]; function* generator(iterator) { for (const el of iterator) { yield el + 1; } } [...generator(generator(generator(array)))].length;
map
const array = [...Array(10000).keys()]; function map(iterator) { return iterator.map(el => el + 1); } [...map(map(map(array)))].length;
loop
const array = [...Array(10000).keys()]; function loop(iterator) { const clone = []; for (let a = 0; a < iterator.length; a++) { clone.push(iterator[a] + 1); } return clone; } [...loop(loop(loop(array)))].length;
