When should I use Observables in Angular?

When should I use Observables in Angular?

You should use Observables in Angular when you need to handle asynchronous data streams, such as HTTP requests or user inputs.

Can you give me an example of using Observables?

Sure! For instance, you can use the HttpClient to fetch data from an API, which returns an Observable that you can subscribe to.

What are the advantages of using Observables over Promises?

Observables are more powerful than Promises as they can handle multiple values over time, support operators for transformation, and can be canceled.

Are there any performance considerations I should be aware of?

Yes, while Observables are efficient, be cautious with memory leaks. Always unsubscribe from Observables when they are no longer needed.
