Lazy loading in React delays loading components, images, or routes until needed.
Benefits of lazy loading include faster initial page loads, reduced bandwidth usage, improved user experience, and scalable architecture.
Implement lazy loading in React using React.lazy() + Suspense at the component level.
Route-based loading in React Router allows lazy loading of routes.
Lazy loading images and components is possible with libraries like react-lazyload.
Dynamic imports can be used with buttons or interactions to load components lazily.
Best practices for lazy loading include loading only non-critical code, pairing with fallback UI, preloading components, handling errors with Error Boundaries, and testing on real devices.
Successful lazy loading can reduce initial payloads, enhance perceived responsiveness, and maintain app scalability, but improper implementation may introduce complexity.
Consider adding lazy-loaded routes or images to your React project for improved loading times.
