Benchmark: for vs forEach vs for in vs for of vs lodash vs for reverse (2)

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.15/lodash.min.js"></script>

Script Preparation code:

var arr = [];

function doMath(a) {
  return Math.log(a);
}

for(i=0; i<10000; i++){
  arr[i] = i + 1;
}

Tests:

forEach
let sum = 0; arr.forEach((value) => { sum += doMath(value); });
for in
let sum = 0; for(const index in arr) { sum += doMath(arr[index]); }
for
let sum = 0; for(var i = 0; i < arr.length; i++) { const value = arr[i]; sum += doMath(value); }
for of
let sum = 0; for(const value of arr) { sum += doMath(value); }
lodash foreach
let sum = 0; _.forEach(arr, (value) => { sum += doMath(value); });
for reverse
let sum = 0; for(var i = arr.length - 1; i >= 0; i--) { const value = arr[i]; sum += doMath(value); }
