Stopping a shared observable execution

Does calling unsubscribe on connectableObservable subscription clear subscriptions for subA and subB?

Asumming:

• sub = connectableObservable subscription to internal Subject
• subA = obsA subscription to connectableObservable
• subB = obsB subscription to connectableObservable

What should correct usubscribe code look like? ###A

setTimeout(() => {
  subA.unsubscribe();
  subB.unsubscribe();
  sub.unsubscribe();
}, 5000)

###B

setTimeout(() => {
  sub.unsubscribe();
}, 5000)

Hi Tomasz. Unsubscribing from sub will not clear subscriptions A and B, because those are attached to the underlying subject. The subscription sub is attached to the source observable. So you would have to write:

setTimeout(() => {
  subA.unsubscribe();
  subB.unsubscribe();
  sub.unsubscribe();
}, 5000)

That said, usually we don't explicitly call connect(), so this use case is actually rather rare. As we see later on in the course, there are better ways of using multicast so that subscriptions are handled more automatically.
