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

The scheduled() method from the RxJS library can be used to execute code asynchronously on a specified scheduler. Here is an example of how to use the scheduled() function in JavaScript:

index.tsx
import { scheduled } from 'rxjs';
import { async } from 'rxjs/scheduler';

scheduled([1, 2, 3], async).subscribe(
  x => console.log(x),
  err => console.error(err),
  () => console.log('Done!')
);

// Output:
// 1
// 2
// 3
// Done!
234 chars
15 lines

In the example above, the scheduled() method is called with an array [1, 2, 3] and the async scheduler. This creates an observable that emits the values in the array asynchronously on the async scheduler. The subscribe() method is called on the observable to listen to the emitted values. In this case, the emitted values are logged to the console using the console.log() method. Finally, the Done! message is logged to the console when the observable completes.

Note that the async scheduler used in the example above is a commonly used scheduler in RxJS for scheduling asynchronous tasks. RxJS also provides other schedulers, such as the queue scheduler for scheduling tasks on a queue, and the animationFrame scheduler for synchronizing with the browser's animation frame.

Overall, the scheduled() method in RxJS provides a flexible way to schedule tasks and control when they are executed, allowing for more precise and efficient asynchronous programming.
