Higher-Order Observables
Explore higher-order observables in Angular and learn how to use the RxJS switchMap and mergeMap operators to handle observable streams. This lesson guides you through modifying Angular services and components to work with observables, enhancing reactive programming skills for dynamic data handling.
We'll cover the following...
Observables that operate on other observables of observables are called higher-order observables. Higher-order observables have an inner observable that contains the actual values we are interested in using. We can use specific RxJS operators to flatten the inner observable and extract its values. The most used flattened operators in Angular development are the switchMap and mergeMap operators.
The switchMap operator
The switchMap operator takes an observable as a source and applies a given function to each ...
