Tests:

Native array
var sum = 0; for(i=0; i<arr.length; i++){ sum += arr[i]; } console.log(sum);
lodash array
var sum = 0; _.forEach(arr, function (element) { sum += element; }); console.log(sum);
Native foreach
var sum = 0; arr.forEach(value => { sum += value; }); console.log(sum);
Native for of
var sum = 0; for(const value of arr) { sum += value; } console.log(sum);
Native for in
var sum = 0; for(let x in arr) { sum += arr[x]; } console.log(sum);
