for-in
const items = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); let index = 0; for (let i in items) { index++; }
for-of
const items = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); let index = 0; for (let i of items) { index++; }
for
const items = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); let index = 0; for(let i = 0; i < items.length; ++i) { index++; }

map
const items = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); items.map((_, i)=> i++);
