An example of an AI chatbot conversation about advanced RxJS techniques and their applications.
What are some advanced techniques in RxJS?
Advanced RxJS techniques include higher-order observables, multicasting, and using operators like switchMap and mergeMap.
Can you explain how switchMap works?
Sure! switchMap is an operator that maps each value to an observable, and it switches to the latest observable, canceling previous ones.
When should I use mergeMap instead of switchMap?
Use mergeMap when you want to handle multiple inner observables concurrently, while switchMap is for the latest one only.
What are some common pitfalls when using these operators?
Common pitfalls include memory leaks from subscriptions and not handling errors properly, which can lead to unexpected behavior.
