Learn React (or other libs)

Let's get together and build a component in React each week. We can then check out each other's solutions to the challenge and hopefully get better at this development thing. While my goal is to get better at React, other libraries are also welcome. There is so much out there we can learn from.

This is not meant to be a tutorial. There are TONS of those for react already on the web. We are going to start with very simple components and work into more complex scenarios.
