// Solution:

function sum(arr) {
  return arr.reduce((acc, curr) => acc + curr, 0);

// This solution is optimal because it uses the reduce method which is a built in method that iterates over an array and returns a single value.
// The reduce method is more efficient than a for loop because it is a built in method that is optimized for performance.

A.I. Evaluation of the Solution

This is a great solution! The candidate has used the reduce method, which is an efficient way to iterate over an array and return a single value.
