Reacting to this :

RxJS

Three primitives: Observer, Observable, Subject.
Observables end on error.
Provides API to handle errors.
Does not provide API to handle ending.

Rxjs v4 does allow to do any kind of operation on the message received/passed through the operators materialize/dematerialize. As often the case, those operators are poorly documented, but are very useful for library creators, or custom error/completion management. Basically there are three types of notifications : next, error, complete (no surprise right?), and when you dematerialize, you receive those messages without the associated side-effects. When you finish doing what you want with them (modifying, replacing, intercepting), you can materialize behind, and your stream continues as usual.

Then you also have the finally operators, and doOnCompleted I believe in v4 too. I don't know enough of v5 to talk about it. And of course the concat operator, as you mentioned for xstream.

Split RxJs4 and RxJs5? Wdyt?

Current ordering is subjective: from most common operators to less common.
Alphabet ordering is obviously impossible because of multiple columns.

retry and catch aren't in the tables (coming from RxJs).

You can't retry a Promise, but just map strings to http requests that returns an observable that you call retry on and catch, and you have powerful error handling.

I can't find or am not experienced enough yet to do a similar stuff with most.

Help ? 😄
