1. **Performance Optimization**: By implementing code splitting, only the relevant chunk is loaded when the user accesses the specific route. This reduces the initial file size, accelerating application startup.
2. **On-demand Loading**: Grouped chunks enable on-demand loading, where resources are loaded based on the page or feature module, avoiding the need to load all application scripts and resources, thus enhancing page response speed and user experience.
3. **Cache Utilization**: Separating common dependencies and libraries into dedicated chunks allows them to be shared across multiple routes and cached by the browser. When users navigate to other pages, if these common chunks are already cached, they don't need to be reloaded, reducing network requests and speeding up loading.
4. **Simplified Debugging**: During development, if each route's dependencies are isolated in separate chunks, issues can be quickly pinpointed to the corresponding chunk, enabling faster and more precise bug fixing and performance optimization.
5. **Better Adaptability and Maintainability**: As the application scales, loading all resources can result in a very large webpage. By grouping into chunks, functional modules can be organized modularly, leading to a clearer project structure and easier management and maintenance.
