What is the difference between various RxJS operators?

Can you explain the difference between map and switchMap in RxJS?

Sure! The map operator transforms each value emitted by an observable, while switchMap switches to a new observable and cancels the previous one.

When should I use switchMap instead of map?

Use switchMap when you need to handle observables that can emit new values over time, like HTTP requests, where you want only the latest result.

What about mergeMap? How does it differ from switchMap?

mergeMap allows multiple inner observables to run concurrently, while switchMap only keeps the latest one active.

Can you give an example of when to use mergeMap?

Certainly! Use mergeMap when you want to process multiple requests simultaneously, like fetching data from multiple APIs.
