What are some practical use cases for React Hooks?

React Hooks are great for managing state and side effects in functional components. Common use cases include form handling, fetching data, and managing local component state.

Can you give me an example of using useEffect for data fetching?

Sure! You can use useEffect to fetch data when a component mounts. For example:

useEffect(() => {
  fetch('https://api.example.com/data')
    .then(response => response.json())
    .then(data => setData(data));
}, []);

What about using useState for form inputs?

You can use useState to manage form input values. For instance:

const [inputValue, setInputValue] = useState('');

const handleChange = (e) => {
  setInputValue(e.target.value);
};

Are there any performance considerations when using Hooks?

Yes, it's important to avoid unnecessary re-renders. Use memoization techniques like useMemo and useCallback to optimize performance.
