title: Is the 'type' attribute necessary for <script> tags?
body: <p>I've seen both this:</p>
  
  <pre><code>&lt;script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js'&gt;&lt;/script&gt;
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>&lt;script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js'&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Does the type attribute matter in any way?</p>
