Code splitting is a technique in React that breaks the bundle into smaller chunks to load only when necessary, improving performance and user experience.
Benefits of code splitting include improved performance, faster load times, and efficient resource utilization by reducing unnecessary code execution.
Code splitting can be implemented in React using lazy and Suspense for lazy loading components, React Router for splitting code with routes, and Webpack's dynamic imports for dynamic component loading.
Best practices for code splitting include splitting at the route level, lazy loading large dependencies, optimizing bundle splitting, and providing a fallback UI with Suspense for a better user experience.
