#### Sum of array elements

This technical problem involves writing a function that takes an array of integers as input and returns the sum of the integers in the array. An example input and output are provided in the problem statement.

#### Problem

```Given an array of integers, write a function that returns the sum of the integers.
Example input:
[1, 2, 3, 4]
Example output:
10```

#### Solution

This solution is in JavaScript. Our A.I. can create solutions in multiple languages.
```// 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.
