What's the difference between Subject and AnonymousSubject in RxJS 5?
I've searched the internet but didn't find any info about AnonymousSubject.
I've found an example on the web
Subject.create(observer, observable);
Looking into rxjs source code I saw that this creates and AnonymousSubject.
Can you also come up with an example when is good to use AnonymousSubject?
回答1:
The AnonymousSubject doesn't subscribe itself to the source Observable. It just connects the source and destination.
I don't know what a typical use-case for AnonymousSubject looks like but it's used inside Subject.lift().
