Ah, I wonder if it is any different now as I made an attempt with the code I was using prior.

Sorry, I'm still figuring out how this works!

Unfortunately, none of that seems to be of any help. :(

All I get from the test output is "expected +0 to equal 15."
Which I am assuming is saying that the first test does not equal 15.
It seems to work in my replit compiler though.

I am wondering if there is anybody who can look over the code that I have? I've been testing it on an online replit js compiler and it seems to work as the function asks. However, everytime I make an attempt it fails.

Maybe it's because I'm using the "..." rest operator?

Sorry, I am very new to this and don't have anybody I can ask inrl.

I didn't want to post my code publically to avoid spoilers.
