• Sharing state between sibling components
• Component mounting, updating, and unmounting
• Introduction to side effects

7. Advanced Hooks: useRef, useEffect, and useMemo

Master advanced React hooks for performance and side effects.

• useEffect for side effects
• Dependency arrays and cleanup functions
• useRef for DOM access and persistent values
• useMemo for performance optimization
• useCallback for function memoization
• Custom hooks

8. Context API Integration with State and Reducer

Learn global state management with React's built-in Context API.

• Understanding the Context API
• Creating and providing context
• Consuming context with useContext
• Combining Context API with useReducer
