Benefits of React Hooks

Convert Class Component to Functional Component with Hooks

Take a simple React class component that manages state and lifecycle methods and rewrite it using functional components and Hooks.

Expected output: A functional component that behaves identically to the original class component.

Hint: Use useState for state and useEffect for lifecycle methods.

Create a Custom Hook for Form Input

Write a custom hook that manages form input state and validation logic.

Expected output: A reusable hook that can be used in multiple form components.

Hint: Use useState to track input value and provide handlers to update it.

React Hooks were introduced to allow functional components to use state and lifecycle features, simplifying component logic and avoiding the complexity of class components.

Custom hooks promote code reuse by encapsulating common logic, making components cleaner and easier to maintain.

No, Hooks can only be used inside functional components or other custom hooks.
