How can you implement code splitting for React Router routes?
To implement code splitting for React Router routes, you can use React.lazy and dynamic import for the route components. Instead of importing all route components statically at the top of your file, you can define them using React.lazy(() => import('./RouteComponent')). Then wrap your Switch or Routes component with a Suspense component to handle the loading state. This approach ensures that the code for each route is only loaded when a user navigates to that route, improving initial load time.
