Hydration and Lazy-Loading Are Incompatible

If your app is slow, the advice is to lazy-load your code and execute less code on startup. That is excellent advice, but it is much harder than it seems because of how hydration works in today's frameworks.

To prove the point, let's build a simple counter and see how hydration will thwart our ability to lazy load it or minimize the amount of code executed.
