```// 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 is O(n) time complexity.
// It is O(n) because the time it takes to run the function is directly proportional to the size of the input.
// The function will run once for each element in the array.```
