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

The windowCount operator in the RxJS library is used to partition a data stream into an inner stream based on the count of the values emitted by the source stream.

Here's an example of how to use the windowCount operator in JavaScript:

index.tsx
const { fromEvent } = rxjs;
const { windowCount, mergeMap, map } = rxjs.operators;

// Create an observable from a click event
const clicks$ = fromEvent(document, 'click');

// Partition clicks into inner observables with a count of 3
const inner$ = clicks$.pipe(
  windowCount(3), // emit an inner observable for every 3 clicks
  mergeMap(obs => obs.pipe(
    map(event => `Inner stream value: ${event.clientX}`) // map inner stream values
  ))
);

// Subscribe to the inner observables
inner$.subscribe(val => console.log(val));

This code creates an observable from the click event and uses the windowCount operator to partition the clicks into an inner stream based on the count of 3. It then maps the inner stream values and subscribes to the inner observables to log the mapped values to the console.

This is just a basic example of how to use the windowCount operator. You can customize the operator to fit your use case by passing in options for the count and the buffer size.
