title: Unobtrusive JavaScript: <script> at the top or the bottom of the HTML code?
body: <p>I've recently read the Yahoo manifesto <a href="http://developer.yahoo.com/performance/rules.html#postload" rel="noreferrer">Best Practices for Speeding Up Your Web Site</a>. They recommend to put the JavaScript inclusion at the bottom of the HTML code when we can.</p>
  
  <p>But where exactly and when?</p>
  
  <p>Should we put it before closing <code>&lt;/html&gt;</code> or after ? And above all, when should we still put it in the <code>&lt;head&gt;</code> section?</p>
