I never learned much from reading docs.
I learn by comparing. Put two approaches next to each other and the difference clicks instantly. I built the Can't series to turn that into a game: real patterns, real decisions, and a clear explanation every time. Every challenge comes from a real decision I've faced or seen others struggle with. No trivia, no gotchas.
