Conclusion to Our React Form Validation App

Congratulations on completing your Hobby Suggestion Form App using React and Vite. In this final module, we’ll summarize your learning, revisit the finished project, test your knowledge with a few MCQs, and share resources for continuing your React journey.

Learning Outcomes

By building this project from scratch, you’ve gained several key front-end development skills. Let’s review what you accomplished:

• Set up a React project with Vite: You initialized the project using Vite, which provided a modern and fast development setup. This gave you instant feedback while coding and simplified the build process.
• Worked with React components: You structured the app inside a single App component, which included both the form logic and the suggestion results. This demonstrated how React components encapsulate logic, state, and UI.
• Managed state with React Hooks: Using useState, you tracked form inputs (name and interests), stored the dataset from the JSON file, and updated the hobby suggestions dynamically.
• Fetched external data: With useEffect, you loaded the hobbies.json dataset from the public folder at runtime. This introduced you to handling external resources in React apps.
• Handled form inputs and validation: You captured input values with controlled components, required fields for validation, and updated state whenever the user typed. On submit, you prevented default behavior and ran your suggestion logic.
• Implemented custom logic: You created a generateSuggestions function to process user interests, compare them against tags in the dataset, score matches, and sort them into top results. This taught you how to combine algorithmic logic with UI rendering.
• Styled the UI with CSS: Using App.css, you designed a centered layout with gradient backgrounds, card-style forms, hover effects, and animated suggestion results. This gave your app a polished, modern look.

Together, these skills form the foundation for building interactive and user-friendly React applications.

MCQs (Answers at the end)

1. Which React hook did we use to fetch the hobbies.json dataset on mount?
   a. useState
   b. useEffect
   c. useRef
   d. useReducer

    

2. What does the handleSubmit function in the app do?
   a. Resets all inputs to empty
   b. Prevents default form behavior and generates suggestions
   c. Styles the form container
   d. Automatically saves data to local storage

    

3. How are hobbies sorted before being displayed in the suggestions list?
   a. Randomly shuffled
   b. Alphabetically sorted
   c. By score of matched tags (highest first)
   d. By length of the hobby name

    

4. Why do we use controlled components for the form inputs (name and interests)?
   a. To automatically validate input formats
   b. To ensure input values are always synced with React state
   c. To let React style the inputs
   d. To fetch suggestions directly from the inputs

    

5. Where is the dataset (hobbies.json) stored in this project?
   a. Inside App.jsx
   b. In the src folder
   c. In the public folder
   d. Inside the CSS file

Answer Key:
1 → b. useEffect
2 → b. Prevents default form behavior and generates suggestions
3 → c. By score of matched tags (highest first)
4 → b. To ensure input values are always synced with React state
5 → c. In the public folder
