Official Answers to Some Challenges?

This is my first time using a BNR guide. I was wondering, does BNR guide have official solutions or solution examples to their challenges? I know you can find community solutions to some challenges but some challenges there are no community solutions and im pretty deep in the book and the book is relatively new so there isn’t much discussion about the challenges. It would be helpful if there were example solutions to the challenges available.

I don’t remember there being official solutions to the challenges in previous books, so I wouldn’t expect them for this one either. The whole point of the challenges is to make you figure things out for yourself; providing downloadable solutions would run counter to that.
