title: Why am I getting ReferenceError: Response is not defined?
body: <p>I am using node.js with express. I am trying to set up a basic server, but have no idea why I am getting a response error.</p>
  
  <pre><code>var http = require('http');
  
  var myServer = http.createServer(function(req,res){
      response.writeHead(200, {"Content-Type" : "text/plain"});
      response.write('Hello World');
      response.end();
  });
  
  myServer.listen(3000);
  </code></pre>
