Explain this recursion function

JavaScript

Can someone please explain to me how this function works, in steps?

  **Your code so far**

  function multiply(arr, n) {
    if (n <= 0) {
      return 1;
    } else {
      return multiply(arr, n - 1) * arr[n - 1];
    }
  }

A lot of people have already given explanations for this, so I won’t try to do that now. Here’s a good explanation. Replace Loops using Recursion -1 explanation - #56 by JeremyLT
