Why shouldn't you make each component of an application a separate chunk via React.lazy? What problems could this create (with rendering, network, bundle size)?

Making each component a separate chunk via React.lazy seems like a good idea for optimization, but in practice, it can lead to several issues:

1. Increased number of network requests — each chunk loads separately, creating many small requests. This increases connection overhead and can slow down loading, especially on mobile networks.

2. Rendering problems — loading each component separately introduces multiple loading states (suspense), which can cause flickering or delays in UI rendering.

3. Bundle size and code duplication — if components share dependencies, they might end up in multiple chunks, increasing the total amount of data to load.

4. Caching complexity — many small chunks are harder to cache effectively than a few large ones.

The optimal strategy is to split the application into logical parts (pages, large modules) rather than every small component. This reduces the number of requests and improves user experience.
