👨‍💼 We're going to be building a simple user interface and in the process we want to limit unnecessary renders as much as possible (not because it's necessary for this specific application, but because it's a useful exercise for you to learn how to do for when it is necessary).

Right now, when you click the counter button, both the App and Footer components rerender.

But the Footer component doesn't change so that render is unnecessary. So please take advantage of React's element optimization by creating a Footer element outside the App so you can render that inline in the App component.

Make sure to check the before/after using the React DevTools so you know that your work is making a difference.
