**I’ve found a bug in a recursion challenge**

I’ve been trying to solve this exercise but it keeps telling me that i need to use recursion… I think I’m using it explicitly.

**Your code so far**

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