Classic for loop
let sum = 0; for (let i=0; i < array.length; i++) { sum += array[i]; }
Optimised classic for loop
let sum = 0; for (let i=0, len=array.length; i < len; i++) { sum += array[i]; }
While loop
let sum = 0; let i = 0; while (i < array.length) { sum += array[i]; i++; }
Optimised while loop
let sum = 0; let i = 0; let len = array.length; while (i < len) { sum += array[i]; i++; }
Array.prototype.forEach
let sum = 0; array.forEach(num => sum += num);
Array.prototype.reduce
const sum = array.reduce((acc, el) => acc + el, 0);
For - of loop
let sum = 0; for (let el of array) { sum += el; }
For - in loop
let sum = 0; for (let i in array) { sum += array[i]; }
For - reverse loop
let sum = 0; for (let i=array.length - 1; i >= 0; i--) { sum += array[i]; }
while - reverse loop
let sum = 0; let i = array.length - 1; while (i >= 0) { sum += array[i]; i--; }
