Lazy Loading & Code Splitting

Webpack's code splitting is more sophisticated than manual dynamic imports because: 1) It automatically optimizes chunk sizes and dependencies, 2) Handles complex dependency trees and shared modules efficiently, 3) Provides additional features like chunk naming and prefetching, 4) Integrates with the build process for optimal output. Webpack analyzes your entire application to make intelligent decisions about how to split code, ensuring that common dependencies are bundled efficiently and that chunks are optimized for size and caching. This automated approach is generally more efficient than manually managing code splitting through dynamic imports alone.
