• [[React Components]]
  • Functional Components
  • Class Components (briefly understand, mostly outdated now)
• [[Props (Properties)]]
  • Passing props to components
  • Props drilling

**4. [[State Management]]

• What is State?
• Using useState Hook
• Updating state and re-rendering
• Difference between Props and State

**5. [[Event Handling]]

• Handling Events in React (e.g., onClick, onChange)
• Passing functions as props for event handling
• Binding event handlers

6. Conditional Rendering

• Rendering UI conditionally using if-else
• Ternary operators in JSX
• Short-circuit evaluation

7. Lists and Keys

• Rendering lists using .map()
• Importance of Keys in lists

8. Forms in React

• Controlled Components
• Uncontrolled Components
• Handling form inputs (e.g., text, checkbox, radio)
• Form validation

9. React Lifecycle (Optional for Functional Components)

• Class Components Lifecycle Methods (e.g., componentDidMount, componentDidUpdate)
• Comparison with Functional Components

10. React Hooks

• Introduction to Hooks
• Commonly used hooks:
  • useState
  • useEffect
  • useContext
• Advanced Hooks:
  • useReducer

  • Using Redux Toolkit (modern approach)
• Alternative libraries: Zustand, MobX

14. APIs and Async Operations

• Fetching data with fetch or axios
• Handling async operations with useEffect
• Displaying loading states
• Error handling

15. Performance Optimization

• Optimizing re-renders

16. Testing in React

• Unit Testing with Jest
• Testing components with React Testing Library
• Writing snapshot tests

17. Deployment
