Hi!
I’m trying to complete the “Build a Library” project and it returns a “Type Error…is not a function” error message. It also comes up if I remove the .toggleCheckOutStatus() and try just the ratings, and then it tells me that .addRating() is not a function. Since it’s coming up with both, I don’t think the parent class is extending to the child classes. I’ve gone through the project video and do not see any discrepancies, but there’s got to be one somewhere! Please help. Here is my code.
