Welcome back, @Darnell_X_Daniell

Congratulations! Your code works as intended.

There are just two simplifications:

- Use `cat` instead of `catInfo[index]` in the `for...of` loop (line 26)
- Use `index` instead of `cat` in the `if` statement (and change the right side accordingly). Can you find out what I mean?

All the best,  
Michael
