Is it necessary to think about unsubscribe with observable.forEach (subscribed internally by rxjs)

Question

the Angular form valueChanges observable can be used in this form:

form.valueChanges.forEach((v)=>console.log(v))

In this case, do I need to worry about unsubscribing? with forEach, there is no explicit subscribe() in my code. Is that means rx.js or angular will handle the unsubscribe?

forEach subscribes internally, and then returns a promise.

With that promise you have no way to unsubscribe.
