title: How to embed a jquery library in javascript?
body: <p>I have a jQuery library code in jquery.xyz.js . 
  I have an html file which uses the function defined in jquery.xyz.js in this manner . </p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  
  &lt;script type="text/javascript"&gt;
  document.write("This is my first JavaScript!");
  $(function(){ $("ul#xy01").xyz(); }); 
  &lt;/script&gt;
  
  &lt;/body&gt;
  &lt;/html&gt; 
  </code></pre>
  
  <p>But the jQuery is not running, which I am assuming because I haven't loaded the jQuery properly onto the html page. So how do I do it?</p>
