Demystifying RxJS Operators
summary
RxJS has ~50 million downloads per month and over 100 operators; the talk drills into the actual code: the lift architecture creates new observables by wrapping source and storing an operator object, subscribe calls operator.call which wires a custom Subscriber; map is implemented by a MapSubscriber that overrides next with try/catch and forwards error/complete, multicast returns a connectable unless a selector is used, and custom patterns shown (a logging observable and a safe HTTP “safeguard” operator) run as expected.
