how to use the debounce function from lodash in javascript

The debounce function from lodash is used to limit the number of times a function is called, especially for expensive operations such as fetching data, resizing elements, or scrolling. It delays the execution of a function until the user has stopped taking an action for a specific amount of time.

Here is an example of how to use debounce function in JavaScript:

index.tsx
import debounce from 'lodash/debounce';

function fetchData() {
  // your code to fetch data here
}

const debounceFetch = debounce(fetchData, 500); // debounce for 500ms

// call the debounced function on user action
button.addEventListener('click', debounceFetch);

11 lines

In this example, the fetchData function is called when the button is clicked. However, instead of calling the function immediately, it is wrapped in the debounce function and assigned to debounceFetch. The second argument of debounce specifies the time in milliseconds for which the execution of fetchData will be delayed.

By using debounce, the fetchData function is only called after the user stops clicking the button for the specified delay time. This reduces the number of times the function is called unnecessarily and improves the performance of your application.
