RX/JS aka reactive streams
RxJS is an implementation for the reactive programming paradigm which implements mostly the observer and iterator pattern and follows the functional programming ideas.
The pattern actually got a renaissance because it's not completely new but has new implementations in many frameworks and languages like Angular, Akka, Spring and many more.
Reason for that attention actually is (in the JavaScript world), that observables can be cancelled (by rules too) and observables can pass (stream) data on multiple events.
Both aspects are not well realizable using promises e.g. and both were also detected as a huge limitation in the JavaScript community — and so it's worth to get an understanding for reactive programming in general.
We at AOE actually use RxJS in combination with Angular and can fully recommend the approach of observables.
