title: Advantages of node.js  in comparison with other web technologies
body: <p>As I understand, <code>node.js</code> is useful for Java Script programmers, who can now develop in server-side. Besides, some Java Script code can be ported from client-side to server-side.</p>
  
  <p>Are there any other advantages for <code>node.js</code> in comparison with other server-side technologies (Java web frameworks, <code>RoR</code>, <code>Django</code>, etc.) ?</p>
