title: Jsfiddle errors won't show
body: <p>Is there any way for Jsfiddle to output javascript errors, an exception, or anything? I have tried to google this, but nothing seems to be out there.</p>
  
  <p>I need to place <code>alert()</code> s through out my javascript code, so i know approximately where a runtime error has occurred, and then guess what the problem is. Surely there is an output console or something where JSFiddle outputs any error?</p>
