title: My http.createserver in node.js doesn't work?
body: <p>Hello guys i just started learning node.js today and search a lot off stuff on the internet , then try to code in node.js i use these two codes to show me the same result but the last one is show the error on my browser something likes "can not find the page".So please explain to me why?</p>
  
  <pre><code>// JScript source code
  var http = require('http');
  http.createServer(function (req, res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello World\n');
  }).listen(1337, "127.0.0.1");
  console.log('Server running at http://127.0.0.1:1337/');
  </code></pre>
  
  <p>This is working but</p>
  
  <pre><code>// Include http module.
  var http = require("http");
  
  // Create the server. Function passed as parameter is called on every request made.
  // request variable holds all request parameters
  // response variable allows you to do anything with response sent to the client.
  http.createServer(function (request, response) {
     // Attach listener on end event.
     // This event is called when client sent all data and is waiting for response.
     request.on("end", function () {
        // Write headers to the response.
        // 200 is HTTP status code (this one means success)
        // Second parameter holds header fields in object
        // We are sending plain text, so Content-Type should be text/plain
        response.writeHead(200, {
           'Content-Type': 'text/plain'
        });
        // Send data and end response.
        response.end('Hello HTTP!');
     });
  
  }).listen(1337, "127.0.0.1");
  </code></pre>
