Sum of integers in an array

This technical problem deals with finding the sum of integers in an array. An example input is given as [1, 2, 3, 4], and the expected output is 10.


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:

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

// Explanation:
// The reduce method is the most optimal solution because it iterates through the array once and returns the sum of the integers.
// The reduce method is also more readable than a for loop.

A.I. Evaluation of the Solution

The candidate's solution is correct and demonstrates a level of completeness. The candidate's approach is also optimal, making use of the reduce method to iterate through the array only once.
