Hot vs Cold Observables

Paul Taylor (RxJS 5 Contributor) with the best explanation of Hot & Cold Observables yet. https://github.com/ReactiveX/RxJS/issues/1121#issuecomment-169568428

... "cold" and "hot" don't refer to unicast vs. multicast, they refer to the state of the computation. An Observable represents an asynchronous computation (aka, it's a function that can return multiple values between now and infinity).

"Cold" Observables are just like functions which haven't been called (subscribed to) yet. Each time you call it (aka, subscribe to it), you're re-running whatever calculation the Observable performs.

"Hot" Observables are just regular cold Observables that you've shoved a Subject between you and the cold Observable source. When you subscribe to it, you're really subscribing to the Subject over and over. Subjects can have any number of Observers (just like EventEmitter, etc.), but the original cold source has only one Observer (the Subject that's sitting between you and the source).

RxJS 5 vs RxJS 4

ReactiveX/RxJS - (RxJS 5)

This rewrite is meant to have better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.

Reactive-Extensions/RxJS - (RxJS 4)

...is a set of libraries to compose asynchronous and event-based programs using observable collections and Array#extras style composition in JavaScript
