title: Steps to migrate a project to using "strict mode"?
body: <p>What are some things I must verify before taking an existing code base and converting it to <a href="https://developer.mozilla.org/en/JavaScript/Strict_mode" rel="nofollow">Strict Mode</a>?</p>
  
  <p>The project is a website that is designed to run on all browsers from IE 8 and above, and doesn't have a lot of unit tests or a js linter continuous integration setup at this point.</p>
  
  <ol>
  <li>What are some language features to look out for, that our own code, or libraries that we use might be using, that will silently break if I turn on strict mode?</li>
  <li>Is there a code analysis process that can look at my whole project, and point out the specific pitfalls from this migration?</li>
  <li>Any particular browsers I should be worried about? (Well, I guess IE 8 is the usual suspect ... but what exactly to look for in IE's 8 support, or lackthereof, of strict mode?)</li>
  <li>If I'm not looking for raw performance, but first at avoiding bugs ... is strict mode a cost effective way to help early bug detection? </li>
  </ol>
