Ye debounce se kaafi similar lg rha hai 🤔

[virajshinde]

import { useEffect, useState, useRef } from "react";

export const useThrottle = (value, delay) => {
const [thValue, setThValue] = useState(value);
const flag = useRef(true);
useEffect(() => {
if (flag.current) {
setThValue(value);
flag.current = false;
var timer = setTimeout(() => {
flag.current = true;
}, delay);
}
return () => clearTimeout(timer);
}, [value, delay]);
console.log(thValue);

return thValue;
};

if i give cleanup function in hook then why it is not working and updating the ui
