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

The debounce function from the rxjs library in Javascript allows you to delay the processing of events by a specified amount of time, and only process the latest event when a series of events happen in rapid succession.

Here is an example of how to use the debounce function:

index.tsx
import { fromEvent } from 'rxjs';
import { debounceTime } from 'rxjs/operators';

const searchInput = document.getElementById('search-input');
const observable = fromEvent(searchInput, 'keyup');

observable.pipe(
  debounceTime(300),
).subscribe(event => {
  // Do something with the latest event after 300ms of inactivity
});

In this example, the fromEvent function creates an Observable from the keyup events of a search input element. The debounceTime operator is then used to delay the processing of events by 300 milliseconds. The subscribe method is called with a callback function that will handle the latest event after 300ms of inactivity.

Keep in mind that the debounce function will only trigger the callback function for the latest event, so if there were any events in between the current and the previous one they will be discarded.
