I know it's not much, but I made a clock in React. Check it out: React Clock on CodePen. React has been one of those things on my list of "Should probably figure out, but haven't yet" for a while now. I figured I'd just dive in and see what I could make.

The biggest thing that I keep messing up with is using className instead of class

Things Learned

• Components
• Using/Updating State
• Props to pass info to components.

Questions

• getTime = () => {} I beleive this is called an arrow function, right? What is the point of it and how is it supposed to be used?
• For this clock example, within React, what would be the best way to store a users preference for 12 vs 24 hour time? I assume just storing the preference in a cookie? Is there an easy "React-ful" way to do this?
