It's frustrating since the new update

Tell us what’s happening:
I don’t know WHY it keeps telling me this “You should use recursion to solve this problem” when i run the tests for my solution.

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

Challenge: Replace Loops using Recursion

It doesn’t work on Firefox, I don’t know why (a bug, I suppose). I used opera to pass it.


Thankss! It actually worked, I am happy i’m not the only one that faced this little bug. I should be more open to use other browser alternatives from time to time and not just for stupid bugs like this that happen, it doesn’t need to be all perfect but for not be dependent just on a single one you know:))

Happy to help :slight_smile:!

By the way, You’re totally right to use different browsers when You have problems, specially if You would like to be a front end developer, because different browsers may have different implementations of JavaScript (EcmaScript).
