Observables are like promises which provide us with abstractions that help us deal with the asynchronous nature of applications.

Observable is like a stream which allows to pass zero or more events where the callback is called for each event.

Difference between Promise and Observable

Scan()

Scan will show all values emitted on source observable

Reduce()

Reduce will show only the final value emitted on source observable
