    </p>
    <p>Error messages and console.log("message") show up in the console. It can be accessed on chrome through the DevTools. To get to the <a href='https://developers.google.com/web/tools/chrome-devtools/'>DevTools</a> in chrome right-click on the background of a site and choose inspect. You can try it right now on this site, I'll wait...</p>
