Summing the Elements of an Array

This technical problem involves writing a function that takes an array of integers as input and returns the sum of all the elements in the array.

// Solution:

function sum(arr) {
  let sum = 0;
  for (let i = 0; i < arr.length; i++) {
    sum += arr[i];
  return sum;

// This solution is optimal because it uses a for loop to iterate through the array and add each element to the sum variable.
// This solution is O(n) because the time it takes to run is directly proportional to the size of the input.
