Reactive JavaScript at Netflix, Microsoft and the World
summary
Claims concrete wins: Netflix adopts RxJS across devices to handle player buffering and memory cleanup at scale for one-third of US broadband traffic, Slack uses observables for live typing and language detection, and Angular 2 bundles Rx for component lifecycle. Promises fail for cancellation and complex streams, so observables provide retries, cancelation via takeUntil, backpressure and schedulers like requestAnimationFrame. Observables are undergoing standardization and may land in ES, not just a library.
