title: Is it possible to stop JavaScript execution?
body: <p>Is it possible in some way to stop or terminate <a href="http://en.wikipedia.org/wiki/JavaScript" rel="noreferrer">JavaScript</a> in a way that it prevents any further JavaScript-based execution from occuring, without reloading the browser?</p>
  
  <p>I am thinking of a JavaScript equivalent of <code>exit()</code> in PHP.</p>
