Section 1: React Fundamentals
This section lays the groundwork for understanding React. You’ll encounter questions about:
- JSX: Learn how JSX combines JavaScript and HTML-like syntax, enabling you to write UI components easily.
- Components: Understand the differences between functional and class components, including their lifecycle methods.
- Props: Explore how to pass data between components using props, ensuring dynamic and reusable components.
- State: Test your knowledge of local component state and how it influences the rendering of your UI.
- Lifecycle Methods: Assess your understanding of component lifecycle methods in class components and their impact on component behavior.
Section 2: React Component Architecture
In this section, you’ll delve into how to structure your React applications effectively. Topics include:
- Component Structure: Evaluate your knowledge of organizing components within a React app.
- Composition vs Inheritance: Explore the importance of composition in building flexible and maintainable applications.
- Higher-Order Components (HOCs): Understand how HOCs can enhance your components with additional functionality.
- Render Props: Assess your grasp of the render props pattern for sharing code between components.
- Controlled vs Uncontrolled Components: Test your understanding of how to manage form inputs effectively.
Section 3: State Management and Data Handling
This section focuses on how to manage and handle data in React applications. Key topics include:
- Local Component State: Examine your understanding of local vs. global state and how to manage state with the useState hook.
- React Context API: Explore the Context API for managing global state and its advantages over props drilling.
- Redux: Assess your knowledge of Redux for state management, including actions, reducers, and the store.
- React Query: Test your understanding of fetching and caching data with React Query, highlighting the benefits of server-side state management.
- Handling Forms: Explore the differences between controlled and uncontrolled inputs, and test your skills with libraries like Formik or React Hook Form for form handling.
Section 4: Routing, Performance, and Optimization
Here, you’ll dive into advanced topics related to routing and optimizing React applications. You’ll encounter:
- React Router: Evaluate your understanding of routing concepts, including different types of routes and their implementation.
- Code Splitting and Lazy Loading: Assess the importance of code splitting and lazy loading for improving performance in large applications.
- React.memo and useMemo: Test your knowledge of memoization techniques to prevent unnecessary re-renders.
- useCallback: Explore when and how to use the useCallback hook for optimizing event handlers.
- React Profiler: Evaluate your understanding of identifying performance bottlenecks in your applications using the React Profiler.
Section 5: Advanced Features and Tools
In this section, you’ll focus on more advanced features and tools in React. Topics include:
- Hooks Overview: Understand the purpose of various hooks, such as useEffect, useRef, and useContext, and how to use them effectively.
- Custom Hooks: Assess your ability to create custom hooks for reusing logic across components.
- Concurrent Mode: Explore what concurrent mode is and its benefits for improving the user experience in React applications.
- Error Boundaries: Test your knowledge of implementing error boundaries to gracefully handle errors in your app.
- React Suspense: Understand how to use Suspense for loading components asynchronously.
- React Strict Mode: Evaluate your grasp of the purpose of Strict Mode and when to use it for identifying potential problems in your application.
Section 6: Development Workflow and Ecosystem
Finally, this section covers the tools and best practices for React development. Topics include:
- Create React App (CRA): Explore the features of CRA for setting up new React projects quickly and easily.
- Next.js: Understand the benefits of using Next.js for server-side rendering (SSR) and static site generation (SSG).
- Testing React Applications: Evaluate your skills in writing unit and integration tests using Jest and React Testing Library.
- React DevTools: Assess your knowledge of using React DevTools for inspecting component trees and debugging your applications.
- React Native: Explore the differences between React.js and React Native, and test your skills in building simple components for mobile.
- Animation Libraries: Learn about popular animation libraries like Framer Motion and React Spring, and assess your ability to implement basic animations.
