Reactive JavaScript with RxJS
summary
RxJS is presented as a way to turn asynchronous events into composable streams instead of callback chaos, using operators like fromEvent, debounce, map, filter, range, concat, merge, flatMap and fromPromise and loaded via a CDN. A concrete example builds a debounced Wikipedia search/autocomplete wired to key events that become HTTP calls (live demo), and tests replace the HTTP Observable in Jasmine with a mock observer so requests can be asserted.
