title: Chrome freezes on my backbone page: how to debug?
body: <p>The project I'm working on involves a "planning" screen, which is entirely made with backbone.js (the other pages of the app are not).</p>
  
  <p>My issue is that from times to times, chrome freezes and the web view stop responding to any interaction. Sometimes, I can manage to quit chrome itself, but usually the controls does not answer either.</p>
  
  <p>I'm pretty convinced this is related to the js code. It seems to me that when a script takes too much time, or loops indefinitely, Chrome can detect this and interrupt the script. However, since this is not the case, I'm thinking that too many js objects stay in memory.</p>
  
  <p>Whatever the cause is, I would like to know which chrome dev tools can help me here. While I'm not a beginner in js, asides setting breakpoints and calling <code>console.log</code>, I have no idea how to debug JS apps. I'm not opposed to use another browser if the dev tools are more suited. </p>
  
  <p>Thanks a lot for your time !</p>
  
  <p>FTR : This is a rails 3.2.8 app, using mongodb, &amp; Backbone.js 0.9.2. The js code is written in coffeescript. This issue happened on my macbook air 2012 running mountain lion, as well as on the client machine which runs on windows 7. The issue appeared at least on chrome 22 &amp; 23.</p>
