Day 10 was about classes. In my opinion, Paul did a terrific job in explaining the differences between classes and structs.
At least I think I actually understood that these two types handle mutability differently. I never thought about that, to be honest. Everytime I did it the wrong way, the compiler complained and I changed it without basically knowing why I was doing this.
Thank you again for the optional, but nevertheless really interesting additional information.
BAM! 10% done — and I'm still enjoying it more than I thought of in the beginning, to be honest 🙃
