3. API Integration:

   • Fetch product details from a backend service to display on the frontend.

   fetch('https://api.example.com/products')
       .then(response => response.json())
       .then(data => {
           // Display products on the page
       });

4. Performance Optimization:

   • Implement lazy loading for images and code splitting for faster page loads.
