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

The scheduler function from the rxjs library allows you to schedule an action to be executed at a certain time or delay. Here's how to use it:

1. Import the scheduler:

index.tsx
import { Scheduler } from 'rxjs';
34 chars
2 lines

2. Define the action you want to schedule:

index.tsx
const action = () => console.log('Hello World!');
50 chars
2 lines

3. Schedule the action to be executed immediately:

index.tsx
Scheduler.nextTick.schedule(action);
37 chars
2 lines

4. Schedule the action to be executed after a delay of 1 second:

index.tsx
Scheduler.async.schedule(action, 1000);
40 chars
2 lines

5. Schedule the action to be executed using a custom scheduler:

index.tsx
const customScheduler = new Scheduler((action) => {
   setTimeout(() => {
      action();
   }, 2000);
});

customScheduler.schedule(action);

Note that the scheduler function works best with observables, allowing you to schedule actions based on observable events.
