Use Higher Order Observables in RxJS Effectively
|
Learn how to handle higher order Observables with powerful operators like switchMap in this advanced RxJS course. Gain advanced skills in using operators and see real applications of these operations. Perfect for those with some understanding of RxJS. Start now!
If you have used RxJS Observables, it is likely you have seen the flatMap or switchMap operators. They are very powerful operators that can be used in various situations, while being common for dealing with HTTP requests. These operators may look mysterious at first, but turn out to be simple flattening operations on higher order Observables.
In this course you will learn what is a higher order Observable, when does it occur in real applications, and how to handle them with operators like switchMap. Throughout this course we will see real applications of these operations.
Start following this course if you have some understanding of RxJS, but want to gain advanced skills in the art of using operators.
If you’re new to RxJS, we highly recommend the
to begin with, and then
to understand operators.
If you’re an absolute beginner to the concept of Observable and async streams, we highly recommend starting with
.
