title: React app.js stopped working
body: <p>I am introducing myself to react for UI development, and have been working through a number of tutorials. From my most recent one, react-hackernews, I ran into an odd issue. I successfully was able to render the UI from app.js to show the front page while pulling in new stories. However, when I quit running my server and returned to the project later on, app.js would no longer work; the other modules do work i.e NewsHeader.html, NewsList.html</p>
