What Tamagotchis can teach you about generators
summary
Built a functioning web Tamagotchi that struggled when many animations overlapped, tried promises and hit “venerable hell” plus inability to cancel, then rewrites animations as generators, uses a coroutine to yield promises and resume only when timeouts resolve, and delegates nested animations with yield and yield star. The result: idle loops that can be interrupted immediately, animations cancel cleanly, and the demo shows feeding events run without waiting for the idle to finish.
