Does Perl have an operator to exit a function or a last for functions?
sub f {
# some code here
if ($v == 10) {
# goto end of function/exit function/last
}
# some code here
}
A goto could do the trick, but it seams wrong somehow?

Rather than a standard subject (Observable) that just emits values as they come in, a BehaviorSubject emits the last value upon subscribe() . You can also get the last value manually using the BehaviorSubjects getValue() method.
RxJS' pipe() is both a standalone function and a method on the Observable interface that can be used to combine multiple RxJS operators to compose asynchronous operations. The pipe() function takes one or more operators and returns an RxJS Observable.
The BehaviorSubject There are two ways to get this last emited value. You can either get the value by accessing the . value property on the BehaviorSubject or you can subscribe to it. If you subscribe to it, the BehaviorSubject will directly emit the current value to the subscriber.
Use return; to exit a subroutine.
