What is the debounce operator in RxJS?

What is the debounce operator in RxJS?

The debounce operator in RxJS is used to limit the rate at which events are emitted. It delays the emission of values until a specified time has passed without another value being emitted.

Can you give me an example of how to use debounce in a search input?

Sure! You can use debounce in a search input like this:

import { fromEvent } from 'rxjs';
import { debounceTime, map } from 'rxjs/operators';

const searchInput = document.getElementById('search');

fromEvent(searchInput, 'input')
  .pipe(
    debounceTime(300),
    map(event => event.target.value)
  )
  .subscribe(value => {
    console.log('Searching for:', value);
  });

What happens if I set the debounce time too high?

If you set the debounce time too high, the user may experience delays in seeing the results of their input, which can lead to a frustrating user experience.
