What are some common RxJS operators used in Angular?

Some common RxJS operators in Angular include map, filter, mergeMap, switchMap, and catchError. They help manage asynchronous data streams.

Can you explain how the switchMap operator works?

Sure! The switchMap operator is used to switch to a new observable and cancel the previous one. It's useful for handling user input, like search queries.

When should I use mergeMap instead of switchMap?

Use mergeMap when you want to handle multiple inner observables concurrently, while switchMap is better for scenarios where you only need the latest result.

Are there any performance considerations when using these operators?

Yes, using switchMap can improve performance by canceling previous requests, while mergeMap can lead to higher resource usage if many observables are active.
