useState, useEffect & Custom Hooks
Moving beyond classes. Managing local state and side effects with the primary React hooks.

Custom Hooks
The real power of React is logic reuse. By creating Custom Hooks, you can extract complex state logic (like fetching or form handling) into reusable, testable functions.
