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

The scheduler function in the rxjs library allows you to control the timing and execution of observables. Here's an example of how to use it in TypeScript:

index.ts
import { Observable, Scheduler } from 'rxjs';

const myObservable = new Observable(observer => {
  observer.next('Hello World');
  observer.complete();
}).subscribeOn(Scheduler.async);

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

In this example, we import the Observable and Scheduler classes from the rxjs library. We create an observable myObservable that emits a single value of 'Hello World' and completes.

We then use the subscribeOn() method to specify that the observable should be subscribed to using the async scheduler. This means that the observable will be executed asynchronously.

Finally, we subscribe to myObservable and log the emitted value to the console.

You can also use other schedulers like queue, animationFrame, asyncScheduler, etc., depending on your use case.
