title: How many copies of code is bundled in the final bundle.js?
body: <p>I am trying to find out how many copy of jquery is included, if I use</p>
  
  <pre><code>var jquery = require('jquery');
  </code></pre>
  
  <p>at the beginning of many js files packed by Webpack.</p>
  
  <p>I think it should be only one. Is this correct?</p>
