title: Simple Node.js example not working in Windows 7
body: <p>I am seeing some demos of node js</p>
  
  <pre><code>setInterval(function(){
      console.log('world');
  }, 2000);
  
  console.log('hello');
  </code></pre>
  
  <p>I have installed node js for Windows, this prints hello and then world when I run it from command prompt as per instruction at a regular interval but within that interval I am not able to do anything. Am I missing something in <strong>Windows 7</strong></p>
