Question - What is RxJS Map, and what do you understand by Higher-Order Observable Mapping?
Answer -
RxJS map operator facilitates us to project the payload of the Observable into something else. We can see the powerful features of Observables when we start using Rx operators to transform, combine, manipulate, and work with sequences of items emitted by Observables.
RxJS Higher-Order Observable Mapping
We map source observable emitted value into other Observable in higher-order mapping instead of mapping a flat value like 1 to another value like 10.! The result is an Observable higher order.
