What is the best practice for route-based code splitting in React?
The best practice for route-based code splitting in React is to lazy load components based on routes. This approach loads only what's needed for the current page the user is viewing. Since routes naturally correspond to separate pages in your application, they make ideal splitting points. Users only need the code for the current route, and you can preload the code for likely next routes. This creates a good balance between performance and user experience, as it reduces initial load time while maintaining smooth navigation.
