Raw
rxjs-higher-order-maps.md

From Reactive Patterns for RxJS with Angular Chapter 7: Transforming Streams

Operator Use Case
concatMap If the order is important and you need to process operations in sequence while waiting for completion.
mergeMap If the order is not important and you need to process operations in parallel to enhance performance.
switchMap If you need to put a cancellation logic to release resources and take always the most recent information.
exhaustMap To ignore new observables while the current one is still ongoing.
