Conquering Time with Functional Reactive Programming
summary
Treats events as sequences and uses RxJS observables to replace ad hoc listeners and promise-only flows with composable pipelines; examples include counting right-side clicks with fromEvent → filter → take → subscribe, a Wikipedia autocomplete that throttles, deduplicates and uses switchLatest drops stale responses to keep results consistent, a drag-and-drop built from mouseDown/mouseMove/mouseUp streams, and testable timing via schedulers let tests simulate async while Rx composes operators into a single efficient loop.
