Describe your issue in detail here.

  **Your code so far**

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

console.log(sum(3, 0))

if (n < 0) {
return 1;
}

I think you need to look at your base case again. The first test is:

“sum([1], 0) should equal 0.”

This is testing the base case. If you pass in the number 0 for the second argument the function should return 0, no matter what is in the array. Your base case needs to handle this.
