Observables has the function of warning/notifying the angular whenever a change occurs in them, so it is very common to use Observables for http requests for example. It is very similar to a Promise, both are asyronous, but the difference is that it can be constant, it can notify the angular several times during its cycle.
I recommend you do this course on angular. It’s really good! For me, it’s the best of the internet.
