Benchmark: javascript loops with reduce 5

Tests:

foreach
const items = Array.from({length: 100000}, () => Math.floor(Math.random() * 40)); let index = 0; items.forEach(i => index++);
for-in
const items = Array.from({length: 100000}, () => Math.floor(Math.random() * 40)); let index = 0; const newArray = []; for (let i in items) { newArray.push(i); }
for-of
const items = Array.from({length: 100000}, () => Math.floor(Math.random() * 40)); let index = 0; const newArray = []; for (let i of items) { newArray.push(i); }
for
const items = Array.from({length: 100000}, () => Math.floor(Math.random() * 40)); let index = 0; const newArray = []; for(let i = 0; i < items.length; ++i) { newArray.push(items[i]); }
optimized-for
const items = Array.from({length: 100000}, () => Math.floor(Math.random() * 40)); let index = 0; const newArray = []; for(let i = items.length; i > 0; --i) { newArray.push(items[i]); }
reduce
const items = Array.from({length: 100000}, () => Math.floor(Math.random() * 40)); items.reduce((acc,value) => { acc.push(value); return acc; }, new Array());
