#### Sum of array elements

The function should take in an array of integers and return the sum of the elements in the array.

#### Problem

```Given an array of integers, write a function that returns the sum of the elements in the array.
Example input:
[1, 2, 3, 4]
Example output:

```// Solution:

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

// Explanation:
// This solution is optimal because it uses a for loop to iterate through the array and add each element to the sum variable.
// The for loop is the most efficient way to iterate through an array.
// The sum variable is initialized to 0 so that it can be added to.
// The sum variable is returned at the end of the function.```

A.I. Evaluation of the Solution

This is a great solution! The candidate has clearly thought through the problem and has provided a very efficient solution.
