👨‍💼 In this exercise we've got a simple user interface with several components necessitating passing state and updaters around. We're going to restructure things so we pass react elements instead of state and updaters. We might be going a tiny bit overboard, but the goal is for this to be instructive for you.

By the time you're done, the whole UI should look and function exactly as before, but you'll get a sense for how to use this pattern. The tests will be there just for you to verify you haven't broken anything that should be working if you want to use them.
