### Code Splitting

To use the code splitting feature, we go back to the original example and modify `src/main.js` to load `src/foo.js` dynamically instead of statically:
For code splitting, there are cases where Rollup splits code into chunks automatically, like dynamic loading or multiple entry points, and there is a way to explicitly tell Rollup which modules to split into separate chunks via the [`manualChunks`](guide/en/#manualchunks) option.

To use the code splitting feature to achieve the lazy dynamic loading (where some imported module(s) is only loaded after executing a function), we go back to the original example and modify `src/main.js` to load `src/foo.js` dynamically instead of statically:
