In rxjs what exactly does the observer.complete() do after observer.next() ?

The observer's complete() callback specifies the action to take when the observable has completed producing and emitting data. const observer = { complete: () => console. log('You have used up all the vowels.')
1. Complete Observer. This is a detached observer where the researcher is neither seen nor noticed by participants. It's one way of minimizing the Hawthorne Effect as participants are more likely to act natural when they don't know they're being observed.
Observers are simply a set of callbacks, one for each type of notification delivered by the Observable: next , error , and complete . The following is an example of a typical Observer object: const observer = { next: x => console. log('Observer got a next value: ' + x), error: err => console.
Observer : Any object that wishes to be notified when the state of another object changes. Observable : Any object whose state may be of interest, and in whom another object may register an interest.
From the documentation observer.complete notifies the Observer that the Observable has finished sending push-based notifications.
In the other hand, observer.complete it's a callback function and an Observable calls this method after it has called next() for the final time, if it has not encountered any errors.
