Flatten a Higher Order Observable with RxJS switch
To consume the higher order RxJS Observable, we had to do a subscribe inside a subscribe. In this lesson, we will learn a better approach using flattening operators, of which switch() is a common and simple one.

Is there any way you can include examples with real data?

Hi Rene. Yes, keep on watching the course and in the 5th lesson from now, there is a real-world example for HTTP requests with switch().

Why is it called switch? It looks like it just flattens.

Hi Scott. It performs flattening, and it's called switch because it is one of the flattening strategies, to "switch from the previous inner Observable to the next inner one".
