Create a Custom Hook and Currency Converter Project | Chai aur React #11 Summary

In this video, we built a Currency Converter project and explored the creation of custom hooks. Here's what we covered:

1. Project Setup:

   • Set up a new React project with Tailwind CSS.

2. Custom Hook:

   • Purpose: Fetch and manage currency data.

   • Functionality: Retrieves data from a primary API with a fallback option. Handles errors and returns data through a state hook.

3. Component Design:

   • Created a reusable input box component for selecting currencies.

   • Used props to make the component dynamic.

4. useId Hook:

   • Generates unique IDs for elements, useful for handling multiple instances.

5. Performance Optimization:

   • Added key props for list items to enhance rendering performance.

Key Learnings:

• How to build and use custom hooks.

• Managing API data with error handling and fallbacks.

• Creating reusable, dynamic components.

• Optimizing performance with keys and unique IDs.

This project reinforced our understanding of React hooks and component design while applying Tailwind CSS for styling.
