Ravenous Part 1 - Javascript in walkthrough vid doesn't match react source code files

I’ve started the Ravenous project part 1 and i’ve noticed the source code in the React App I generate with make-react-app is different to the walkthrough video that accompanies the exercise.

The App.jss and the index.html files are different to the the walkthrough video and rather than link or list what’s different I really think it would be best to get everything the same starting. Even slight differences are likely to cause an error at some stage.

Does anyone have a workaround or any tips for this?
