title: require().server. Require with a dot in the statement
body: <pre><code>                var WebSocketServer = require('websocket').server;
  </code></pre>
  
  <p>I came across this in some NodeJS code and I don't believe I have ever seen a require with a dot in the statement like this ever before. Is the dot perhaps loading just a portion of the websocket module or is there another meaning to it?</p>
  
  <p>Thanks in advance... </p>
