Which one is the Github organization for reactivex.io?

Question

There are two different organizations linked to reactivex.io:

• https://github.com/ReactiveX
• https://github.com/Reactive-Extensions

I see that Java extensions exist only in ReactiveX.

But, Rx.NET or IxJx exist in both organizations. However the former is active in Reactive-Extensions and the latter more active in ReactiveX.

Why there are two different organizations?

Answer 1

ReactiveX is the repo created for RXJS 5 which is a ground-up rewrite of RXJS for performance purposes.

You can find more details about the changes between the two versions here. My guess is that Rx.NET isn't on ReactiveX yet because they aren't on version 5 yet. It also seems like the various languages are pretty loosely coupled and don't necessarily work too closely together on things like this.
