how to use the objectunsubscribederror function from the rxjs library in javascript

To use the ObjectUnsubscribedError function from the rxjs library in JavaScript, you need to import it from the library like this:

index.tsx
import { ObjectUnsubscribedError } from 'rxjs';

2 lines

Then you can use it in your code to throw an error when an operation is attempted on a closed or unsubscribed observable. Here is an example:

index.tsx
const observable = new Observable((observer) => {
  // Do something here
  return () => {
    // Do some cleanup here
    throw new ObjectUnsubscribedError();
  };
});

const subscription = observable.subscribe(
  (value) => console.log(value),
  (error) => console.log(error),
  () => console.log('Completed')
);

subscription.unsubscribe();

In this example, the observable emits some values and performs a cleanup operation when unsubscribed. The subscription is created from the observable and then immediately unsubscribed. When the cleanup function is called after the unsubscription, it throws an ObjectUnsubscribedError because the observable is already closed.

You can catch this error and handle it appropriately, or let it propagate up the call stack.
