In this section, we are going to start getting into what makes promises and observables different.
Single Use vs Multiple Use
The promises are single event asychronous pipelines, which makes them usable for one instance. Whereas the observables can be set to change continuously at any set intervals. Observables become a reusable asychronous pipeline.
