How can I use observable libraries in my project?

Observable libraries, like RxJS, allow you to work with asynchronous data streams. You can integrate them by installing the library and using observables to manage data flow.

Can you give me an example of how to create an observable?

Sure! In RxJS, you can create an observable using the new Observable() constructor. Here's a simple example:

import { Observable } from 'rxjs';

const myObservable = new Observable(subscriber => {
  subscriber.next('Hello');
  subscriber.next('World');
  subscriber.complete();
});

myObservable.subscribe(value => console.log(value));

What are some common use cases for observables?

Common use cases include handling user input events, managing API calls, and working with real-time data streams like WebSockets.

Are there any performance considerations I should be aware of?

Yes, it's important to manage subscriptions properly to avoid memory leaks. Use operators like takeUntil or unsubscribe to clean up when observables are no longer needed.
