Feeling overwhelmed by React concepts and unsure where to start? You’re not alone. A structured roadmap will help you tackle key React topics efficiently and confidently.

Overcoming Common Interview Prep Pain Points

• Too Many Concepts: Hooks, Redux, Context API—where should you focus?
• State Management Struggles: Managing props, lifting state, and handling global state can be tricky.
• Performance Issues: Optimizing rendering and avoiding unnecessary re-renders is crucial.
• Real-World Application: Building scalable, maintainable React apps requires hands-on practice.
• Lack of Mock Interviews: Many candidates struggle with live coding and system design questions.

Your 4-Week Preparation Roadmap

This roadmap ensures you master React fundamentals, advanced techniques, and best practices.

Week 1: Master React Fundamentals

Focus: JSX, components, props, state, and event handling.

Daily Goals:

• Day 1: Learn JSX, functional vs. class components, and props.
• Day 2: Understand state and event handling in React.
• Day 3: Explore the Virtual DOM and React’s rendering process.
• Day 4: Use useState and useEffect hooks effectively.
• Day 5: Learn conditional rendering and list rendering.
• Day 6: Implement controlled and uncontrolled components.
• Day 7: Build a small React project to apply these concepts. Test yourself using our Interview Question Generator.

Tip: Be prepared to explain the difference between props and state.

Week 2: Advanced React & State Management

Focus: Context API, Redux, and performance optimization.

Daily Goals:

• Day 1: Understand Context API and useReducer.
• Day 2: Learn Redux basics—store, actions, reducers.
• Day 3: Implement Redux Toolkit for state management.
• Day 4: Explore memoization (React.memo, useMemo, useCallback).
• Day 5: Optimize rendering and prevent unnecessary re-renders.
• Day 6: Use React Profiler to debug performance issues.
• Day 7: Build a React project with Redux for global state management.

Tip: Be ready to discuss Redux vs. Context API and their use cases.

Week 3: API Integration, Routing & Testing

Focus: API calls, React Router, unit testing.

Daily Goals:

• Day 1: Fetch data using Fetch API and Axios.
• Day 2: Handle loading, errors, and caching API responses.
• Day 3: Learn React Router for client-side navigation.
• Day 4: Implement authentication and protected routes.
• Day 5: Write unit tests using Jest and React Testing Library.
• Day 6: Mock API requests in tests using MSW.
• Day 7: Build a React app with API integration and routing.

Tip: Expect questions on how to optimize API calls in a React app.

Week 4: System Design & Mock Interviews

Focus: System design, component architecture, and behavioral interviews.

Daily Goals:

• Day 1: Study component composition and reusable patterns.
• Day 2: Learn about design patterns in React (HOC, Render Props, Custom Hooks).
• Day 3: Implement lazy loading and code splitting.
• Day 4: Practice whiteboarding React system design questions.
• Day 5: Solve common React interview questions in a mock setting.
• Day 6: Review behavioral interview questions (STAR method).
• Day 7: Relax, review your portfolio, and prepare for your interview.

Tip: Be ready to walk through your React projects and explain key decisions.
