Keyword - debugger | A practical example
<p>From <a href="https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Statements/debugger" rel="nofollow">MDN</a>.  </p>

<blockquote>
  <p>Invokes any available debugging functionality. If no debugging
  functionality is available, this statement has no effect.</p>
</blockquote>

<p>I've debugged in IE, Safari, and FF and have found no need for this keyword.  Does it have a practical use?  Can someone provide a practical example?</p>
