Benchmark: for vs foreach vs reduce vs for..of

Script Preparation code:

var array = Array.from({ length: 200 }, () => {
  return Math.floor(Math.random() * (32000 - 0 + 1)) + 0;
})

Tests:

for
let result = 0; for (var i = 0; i < array.length; i++) { result += array[i]; } result;
foreach
let result = 0; array.forEach(function(i) { result += array[i]; }); result;
reduce
let result = array.reduce((accumulator, currentValue) => { return accumulator + currentValue; }, 0); result;
for..of
let result = 0; for (var i of array) { result += array[i]; } result;
