🔸 TLDR
▪️ Wrap your fast-changing value in a useDebounce hook
▪️ It only updates after the user stops typing for a delay
▪️ Result: fewer API calls, fewer re-renders, smoother UX 🚀
const useDebounce = (value, delay = 500) =〉 {
const [debounced, setDebounced] = useState(value);
useEffect(() =〉 {
const t = setTimeout(() =〉 setDebounced(value), delay);
return () =〉 clearTimeout(t);
}, [value, delay]);
return debounced;
};
🔸 HOW IT WORKS
▪️ useState stores the debounced value
▪️ useEffect starts a timer every time value or delay changes
▪️ If the user types again before the delay, clearTimeout cancels the previous update
▪️ Only the last “stable” value is returned to your component
🔸 WHERE TO USE IT
▪️ Search bars & filters 🔍
▪️ Autocomplete / typeahead inputs
▪️ Form fields that trigger validation or API calls
▪️ Any place where “every keystroke = 1 request” would be overkill
🔸 TAKEAWAYS
▪️ Debouncing is a tiny pattern with huge UX impact
▪️ This hook is reusable across your app, not tied to one component
▪️ Cleaning up side effects (clearTimeout) is as important as adding them 💡
