ReactDOM in tutorial

[j-funk]

I noticed that the tutorial is using ReactDOM but this repo doesn't have that dependency listed anywhere. Is that because of recent changes with react? or was it intentionally left out?

When I created this repo the current version was 0.13.3. It was not until React v0.14 that React and ReactDOM were splitted in two different packages. So, yes, long time ago there was no react-dom package and that is why you haven't seen that dependency listed anywhere.

Maybe it is time to upgrade this repo to the current version of the tutorial...
