Functional Update When the new state depends on the previous state, use a functional update: const increment = ( ) => { setCount ( prevCount => prevCount + 1 ); }; 3. Updating Multiple State Variables If you have multiple pieces of state, you can update them separately: const [count, setCount] = useState ( 0 ); const [name, setName] = useState ( "" ); const updateCount = ( ) => { setCount (count + 1 ); }; const updateName = ( newName ) => { setName (newName); }; 4. Using an Object to Manage Sta
