title: What is difference between jquery.js and jquery.lite.js?
body: <p>When I download the jQuery zip file <a href="http://jqueryjs.googlecode.com/files/jquery-1.2.5-release.zip" rel="noreferrer">LINK</a>. It gives me 4 different files:</p>
  
  <ul>
  <li>jquery.js</li>
  <li>jquery.lite.js</li>
  <li>jquery.min.js</li>
  <li>jquery.pack.js</li>
  </ul>
  
  <p><code>pack.js</code> is the most compressed one of that js file and <code>min</code> is minified.
  So I have two questions...</p>
  
  <ol>
  <li>What is difference between <code>jquery.js</code> and <code>jquery.lite.js</code>. There looks to be no difference when I view code.</li>
  <li>What is better to use <code>min.js</code> or <code>pack.js</code> on a live website?</li>
  </ol>
