▲ 5 ▼ Announcing RxGo v2
ReactiveX is an API for asynchronous programming based on the observer pattern.
RxGo is the official Go implementation of ReactiveX (a cousin of RxJS, RxJava, etc.).
There are +50 new operators and multiple new features (hot vs cold observable, connectable observable, backpressure, etc.)
Yes, Go has already great concurrency primitives and yes, there is still no generics. Nonetheless, RxGo may still be worth a look ;)
