Script Preparation code:

const smol = 100000; // 100,000 (100 Thousand)
const meed = 10000000; // 10,000,000 (10 Million)
const beeg = 100000000; // 100,000,000 (100 Million)

var size = smol

var arr2 = [];
for (let ii = 0; ii < size; ii += 1) { arr2.push(ii); }

Tests:

Array.forEach (native)
let twice arr2.forEach(function (el, index) { twice = el * 2; });
lodash _.each
let twice _.each(arr2, function (el, index) { twice = el * 2; });
Array.map (native, discarding result)
let twice arr2.map(function (el, index) { twice = el * 2; });
lodash _.map (discarding result)
let twice _.map(arr2, function (el, index) { twice = el * 2; });
for loop (x of arr)
let twice for (const el of arr2) { twice = el * 2; }
for loop (indexed)
let twice for (let ii = 0; ii < arr2.length; ii += 1) { twice = arr2[ii] * 2; }
