Subscribe is an method in RxJS library and is used with observables.
The subscriber function defines how to obtain or generate values or messages to be published.
You create an Observable instance that defines a subscriber function, which is called when a consumer calls the subscribe() method
To execute the observable you have created and begin receiving notifications, you call its subscribe() method, passing an observer. This is a JavaScript object that defines the handlers for the notifications you receive. The subscribe() call returns a Subscription object that has an unsubscribe() method, which you call to stop receiving notifications.
