What is a potential downside of excessive code splitting?
A potential downside of excessive code splitting is that it can lead to too many network requests, which may harm performance rather than improve it. Each split chunk requires a separate HTTP request when needed, and there's overhead associated with each request. If you split your code into too many small chunks, the latency from multiple requests can outweigh the benefits of loading smaller files. Finding the right balance is key - chunks should be meaningful groupings of related functionality that are large enough to justify the overhead of a separate request.
