An example of an AI chatbot conversation about the distinctUntilChanged operator in RxJS.
What is the distinctUntilChanged operator in RxJS?
The distinctUntilChanged operator in RxJS is used to filter out consecutive duplicate values emitted by an observable.
Can you give me an example of how to use it?
Sure! Here's a simple example: source$.pipe(distinctUntilChanged()) will only emit values that are different from the last emitted value.
What happens if the values are objects?
If the values are objects, distinctUntilChanged will only consider them distinct if their references are different. You may need to use a custom comparison function.
