How to use throttle or debounce with React Hook?

Question

I\'m trying to use the throttle method from lodash in a functional component, e.g.:

const App = () => {
  const [value, setValue

Here's a simple hook to debounce your calls.

To use the below code, all you have to do is declare it as so

const { debounceRequest } = useDebounce(someFn);

And, then call it as so

debounceRequest(); 

Implementation is shown below

import React from "react";

const useDebounce = (callbackFn: () => any, timeout: number = 500) => {
const [sends, setSends] = React.useState(0);

const stabilizedCallbackFn = React.useCallback(callbackFn, [callbackFn]);

const debounceRequest = () => {
  setSends(sends + 1);
};

// 1st send, 2nd send, 3rd send, 4th send ...
// when the 2nd send comes, then 1st set timeout is cancelled via clearInterval
// when the 3rd send comes, then 2nd set timeout is cancelled via clearInterval
// process continues till timeout has passed, then stabilizedCallbackFn gets called
// return () => clearInterval(id) is critical operation since _this_ is what cancels 
//  the previous send.
