How can I optimize RxJS performance in my application?
To optimize RxJS performance, consider using operators like debounceTime
, distinctUntilChanged
, and switchMap
to reduce unnecessary emissions.
What are some common pitfalls to avoid when using RxJS?
Common pitfalls include creating too many subscriptions, not unsubscribing properly, and using heavy operators that can slow down performance.
Can you explain the difference between mergeMap
and switchMap
?
Certainly! mergeMap
subscribes to all inner observables and emits their values, while switchMap
only subscribes to the latest inner observable, canceling previous ones.
How can I measure the performance of my RxJS streams?
You can use tools like the RxJS DevTools or performance profiling in your browser to analyze the execution time and memory usage of your streams.
