Why Should You Care About Higher Order Mapping Operators
This session examines several higher-order mapping operators using real-world scenarios.
What you'll learn
What is a higher-order mapping operator? When would you use one? Why should you care? There are important differences between the map operator and higher-order mapping operators, such as concatMap, mergeMap, and switchMap. For example, higher-order mapping operators automatically subscribe to their inner Observables. This session examines several higher-order mapping operators using real-world scenarios. If you’ve ever wondered why you use a switchMap instead of a map, what an “inner Observable” is, or what a higher-order mapping operator does, this session is for you.
