Script Preparation code:
function* range1(a, b, n = 1) { for (let i = a; i < b; i += n) yield i; } function range2(a, b, n = 1) { return Array.from({ length: Math.ceil((b - a) / n), map: (_, i) => start + i * n }); }
Tests:
Generator
let nn = 0; for (const n of range1(0, 10000, 5)) nn++;
Array
let nn = 0; for (const n of range2(0, 10000, 5)) nn++;
Raw loop
let nn = 0; for (let i = 0; i < 10000; i += 5) nn++;
