Replace Loops using Recursion2

JavaScript
1

Tell us what’s happening:
Describe your issue in detail here.
Write a recursive function, sum(arr, n), that returns the sum of the first n elements of an array arr. Also -Your code should not rely on any kind of loops (for or while or higher order functions such as forEach, map, filter, or reduce.). e.g sum([2, 3, 4, 5], 3) should equal 9.

  **Your code so far**

function sum(arr, n) {
// Only change code below this line
function sum(arr, n) {
if(n <= 0) {
  return 0;
} else {
  return sum(arr, n - 1) + arr[n - 1];
}
}
// Only change code above this line
}

Ok, you copy-pasted the challenge description, but what do you need help with?

It looks a heck of a lot like you copy-pasted the answer you found somewhere into the function instead of writing your own. Unfortunately, the way you copy-pasted the answer is preventing it from working.

Alright what’s the correct answer
