Consider the following situation:
this.http.call().pipe(
catchError((error) => {
takeAction();
}),
switchMap((data) => {
performAdditionalTasks();
}),
);
Is it feasible for the switchMap function to be skipped or not executed if the catchError block is activated?
The outcome is determined by the type of Observable that is returned from the callback function of catchError.
If you return empty(), then it will not activate switchMap because empty() only completes without emitting any next notifications.
Alternatively, you can opt to return throwError(...) which only emits an error notification without any next notifications.
