RxJS 5 In Modern Web Applications
summary
RxJS 5 is presented as a performance- and spec-focused rewrite and shows concrete patterns: observables are just functions (you return a teardown), operators are higher-order functions, and a working drag‑and‑drop is built from composing three event streams. Error handling requires placement specifics — put catch inside switchMap to avoid killing the outer polling stream — and subscription management strategies include declarative takeUntil, single-subscription composition, or framework helpers like Angular 2’s async pipe with share for multicasting.
