+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 think that it's worth to dive deeper into this paradigm.
