Reactive Programming Demystified Drink the Kool-Aid
summary
Claims that RxJS makes app code portable across frameworks and future proof and then shows it: demos include RxJS multiplexing over WebSocket with groupBy and timer to animate per-request "Ken" heads, a drag and drop implemented with Subjects and takeUntil in React Native, plus examples of observables, operators, and shareReplay. Covers how observables differ from promises, Angular/ngrx integration, EventTarget observable proposal in WHATWG/TC39, and teardown via unsubscribe.
