Ask yourself what your defined and declared variables are.

I know, I think I figured it out, the syntax for .map was way off,
thnx for your reply

No, it simply means the error messages that you are seeing on the left (expected, actual). I can tell you for one that your map is returning nothing, so that can't be good.

Hi sorry, I'm new here.
what's the assertion message ?

did you mean I wrote some spoilers that could ruin it for the other wariors?

Hi,

Did you look at the assertion message? you have a lot of stuff that shouldn't be in the resulting string, for now.
