Hooks help you avoid duplicating state and lifecycle code across components by providing a clean way to reuse stateful logic in functional React.
useState for local state and useEffect for side effects instead of class lifecycle methods.use... custom hooks so multiple components can share the same logic.useMemo/useCallback.Create a custom hook that wraps your shared state and side-effect behavior using useState and useEffect, then call it from each component that needs that logic.

To extract shared React Hook logic, encapsulate the duplicated stateful behavior into a custom hook using `useState` and `useEffect`, then call that custom hook from each functional component that needs it.
The Rules of Hooks require calling hooks only at the top level of your React functions and never inside loops or conditions. They apply to custom hooks to prevent subtle runtime bugs during state and side-effect management.
You manage side effects in functional components by using the `useEffect` hook instead of class lifecycle methods, allowing you to handle subscriptions and other side-effect behavior cleanly within your custom hooks.
You do not need `useMemo` or `useCallback` for every variable in custom hooks. It is better to prefer derived state during render and rely on React compiler memoization instead of applying unnecessary manual memoization.
Yes, you can use `useState` and `useEffect` to handle form state by encapsulating the form handling logic into a reusable custom hook, which multiple components can then call to share the exact same stateful behavior.
You should prefix reusable hook functions with `use` to signal to React that they are custom hooks. This enforces the Rules of Hooks and ensures correct execution of state and side-effect logic.
