Benchmark: Array sum with 7 diff loops

Script Preparation code:

var
  arr = Int32Array.from({ length: 1000 }, (_, i) => i),
  fun = n => 3 * n >> 1,
  res = 0;

Tests:

regular for (;;)
const array = arr, len = arr.length; for (var i = 0; i < len; res += fun(array[i++])); console.log('for (;;):', res, res = 0);
for..in
const array = arr; for (const i in array) res += fun(array[i]); console.log('for (in):', res, res = 0);
for..of
for (const v of arr) res += fun(v); console.log('for (of):', res, res = 0);
forEach()
arr.forEach(v => res += fun(v)); console.log('forEach():', res, res = 0);
map()
arr.map(v => res += fun(v)); console.log('map():', res, res = 0);
reduce()
res = arr.reduce((a, v) => a + v); console.log('reduce():', res, res = 0);
