This question explores Web Development and addresses practical considerations related to: How can I optimize image loading for better performance in a React app?

Optimizing image loading in a React app can significantly enhance performance by reducing load times and improving user experience. Techniques such as lazy loading, using responsive images, and leveraging modern image formats can be effectively applied within the React framework. import React from 'react'; const ImageComponent = () => ( ); export default ImageComponent; ADDITIONAL COMMENT: Use the "loading='lazy'" attribute to defer off-screen images until a user scrolls near them. Implement responsive images with "srcSet" and "sizes" to serve different image resolutions based on device characteristics. Prefer modern image formats like WebP for better compression without quality loss. Consider using a CDN to deliver images faster by caching them closer to users. Optimize image dimensions and compression before uploading to reduce file size. ✅

        alt="Description"
        loading="lazy"
      />
