Understanding High Order Observables
summary
Explains concrete behavior of observables of observables using High Order Observables, demonstrates the core claim that marble tests give deterministic control over cold vs hot timing and subscription windows, shows the tooling (rxjs marbles / TestScheduler and StackBlitz demos) used to assert operator outputs, enumerates surprising scale — about 120 operators to explore — and walks through examples where switchMap cancels inner streams while mergeMap merges them, with passing and failing marble tests.
