RxJS Schedulers from Outer Space – Performance, Animations, Asynchrony
summary
Covers concrete RxJS 7 changes and tools: a reduced max-frame-count and a new VirtualTimeScheduler, plus demos like a realtime signature pad using animationFrame scheduling. Shows techniques for smooth animations, deterministic reproduction of race-timing bugs via virtual time, explains subscribe/observer execution ordering and the subscribe scheduling parameter, and demonstrates refactors/tests that run orders of magnitude faster than real time.
