What is the difference when using throttle and useeffect settimeout for search

Question

I am using useEffect and its working fine, but I am aked to use debounce insted. Should I just make the useEffect into a seprate/ reusable function?

const [query, setQuery] = useState('');

useEffect(() => {
    const delayDebounceFn = setTimeout(() => {
      // Perform search operation
      console.log(`Searching for: ${query}`);
   }, 1000); // Delay search by 1 second

  return () => clearTimeout(delayDebounceFn);
}, [query]);

const handleInputChange = (event) => {
    setQuery(event.target.value);
};

To answer your question: Yes.

Go for useEffect function, if data to be fetched or manipulated when dependent object changes

useEffect(<function>, <dependency>)

useEffect(() => {
  //Runs only on the first render
}, []);

useEffect(() => {
   //Runs when the dependent object changes.
}, [dependent object (like queryparameter]);

but in cases like, user is typing in searchbar then it make sense to delay the fetching of records for ,let's say, microseconds.

function debounce_leading(func, timeout = 300){
  let timer;
  return (...args) => {
    if (!timer) {
      func.apply(this, args);
    }
    clearTimeout(timer);
    timer = setTimeout(() => {
      timer = undefined;
    }, timeout);
  };
}

Hope this helps
