Learning Outcomes of the Project

Congratulations on completing your very own interactive Quiz App using React and Vite. This module wraps up the project by walking you through the major takeaways, showing the final product, testing your understanding with MCQs, and sharing useful resources for future learning.

Learning Outcomes of the Project

By building this quiz app from start to finish, you've covered a wide range of essential front-end skills. Here’s what you’ve accomplished:

1. Set up a modern React project with Vite: You bootstrapped a React app using Vite, which provides a fast development environment with optimized build time and hot module replacement.
2. Built reusable and interactive components: You created modular components like Quiz, QuestionCard, CategorySelector, and WelcomeScreen, helping you understand how to break down UIs into logical pieces.
3. Used React state management and hooks: You worked extensively with React Hooks like useState and useEffect to handle quiz state, fetch API data, track scores, and update the UI in real-time.
4. Integrated live APIs for real-world data: Questions were fetched dynamically from the Open Trivia DB API, making the quiz content dynamic and always changing. You even fetched the list of categories from the API.
5. Handled user input and feedback: Users could select a domain before starting, answer multiple choice questions, and receive instant feedback on whether their answers were correct. The app also shows a final scorecard.
6. Applied styling and animations: The app features a dark theme with modern UI styling, responsive buttons, hover animations, layout spacing, and visual feedback using colors and transitions.
7. Displayed a professional scorecard: At the end of the quiz, a well-structured table shows all questions, selected answers, correct answers, and an overall score in a user-friendly way.
8. Deployed with Netlify: You successfully deployed your app using Netlify, making it accessible online for anyone to try out.

With these skills, you are well-equipped to build, style, and deploy real-world applications using modern React workflows.

MCQs (Answers at the end)

1. What hook was used to fetch trivia data from the API when the component mounted?
   a. useRef
   b. useState
   c. useEffect
   d. useMemo
2. What is the purpose of the shuffle() function in the quiz app?
   a. Style the questions
   b. Randomize the order of options
   c. Fetch new questions
   d. Submit the answers
3. Where is the category list fetched from?
   a. React API
   b. Netlify
   c. Vite
   d. Open Trivia DB API
4. What does the decodeHtml() utility function do?
   a. Runs animations
   b. Converts encoded HTML into readable text
   c. Submits user answers
   d. None of the above
5. How does the app display whether a user's answer was correct or incorrect?
   a. Through alerts
   b. By navigating to a new page
   c. By color-coded buttons and scorecard
   d. By console logs

Answer Key:

1. c – useEffect is used to perform side effects like fetching data after the component mounts
2. b – shuffle() ensures the options appear in a random order for each question
3. d – The category list is fetched from Open Trivia DB’s category endpoint
4. b – Some API responses contain HTML entities that need to be decoded to plain text
5. c – Answers are styled as green/red and listed clearly in a result table with correct status
