function is a void type but the instructions ask me to return something?

amazing thankyou!

Thanks! I kicked myself a few times and added a ternery at the bottom to handle this.
But now it fails because it received 0 but expected -4

edit: I had written an incorrect test XD

My code is passing some tests but a couple of them are kicking back. Logs and test below, I can't make sense of it!
I think the test value is incorrect in this case?

Log
Question 1:
Wrong answer, -1 point
Score is now -1

Question 2:
blank answer, 0 points
Score is now -1

Question 3:
blank answer, 0 points
Score is now -1

Question 4:
Wrong answer, -1 point
Score is now -2

total points is -2

Test Failed
Should return 0 with ["b", "d", "a", "c"] and ["a", "", "", "b"]
Expected: 0
But was: -2

because you haven't returned anything?

I hadn't even finished this, why is it here?

nice simple regex solution to replace the word, but how does it return the string?
