What method is most effective for generating an Observable that emits immediately upon instantiation?

I'm pondering the best and most semantically proper way to create an observable that emits immediately upon creation.

While I could use of(unknown), of(undefined), of(null), of(true), etc., I'm curious if there is a more "correct" approach or any recommended references for this scenario?

Answer №1

.of() is the proper method to use, which is why it has been included in this code.

Answer №2

To start, you will need to instantiate a new BehaviorSubject class that extends the Subject, which itself is a subclass of Observable.

When creating an instance of this class in the constructor, you can specify a value that will be emitted upon instantiation.

example: BehaviorSubject<string> = new BehaviorSubject<string>('initial value');
