how to use the scheduled function from the rxjs library in typescript

To use the scheduled function from the RxJS library in TypeScript, you can follow these steps:

1. Import the necessary modules:

index.ts
import { scheduled, OperatorFunction, Observable } from 'rxjs';
import { subscribeOn } from 'rxjs/operators';

2. Define a function that returns an Observable:

index.ts
function myObservable(): Observable<number> {
  return new Observable<number>((observer) => {
    observer.next(1);
    observer.next(2);
    observer.next(3);
    observer.complete();
  });
}

3. Use the scheduled function to schedule the Observable using the ES6 scheduler:

index.ts
scheduled(myObservable(), subscribeOn(asyncScheduler)).subscribe({
  next: (value) => console.log(value),
  complete: () => console.log('Complete!'),
});

In this example, the myObservable function returns an Observable that emits the values 1, 2, and 3. The scheduled function takes two arguments: the first is the Observable to schedule, and the second is an OperatorFunction that applies a scheduler to the Observable. We use the subscribeOn operator to specify that we want to use the asyncScheduler to schedule the Observable.

Finally, we subscribe to the scheduled Observable and log its values to the console when they arrive. When the Observable completes, we log the message "Complete!".
