Reactive Programming in Angular with RxJS
summary
Introduces using RxJS 5 inside Angular to build and manipulate Observables: creating streams with of/from/create, converting Promises, and using operators like map, filter, take, retry. Explains flattening strategies (switchMap, mergeMap, concatMap), hot vs cold streams and multicasting with publish/connect, shows marble diagrams and that operators return new Observables, and stresses unsubscribing to avoid memory leaks while wiring event streams into Angular.
