Can you please tell me where you found response object? http.createServer return a callback function which have two arguments. They are response and request. response use for send data/information to client and request use for get data/information from client. So in your http.createServer callback function add response and request arguments. After that in callback function use response object. Like this. 

var http = require("http");
var server = http.createServer(function(request, response) {
    response.writeHead(200, {
        "content-Type" : "text/html"
    });
    response.end("Hello again");
 }).listen(8888);

You never accept the "request" variable. Below is a working version of what you're attempting.

var http = require("http");
var server = http.createServer();

server.on('request', function(request, response) {
   response.writeHead(200, {
    "content-Type" : "text/html"
   });
  response.end("Hello again");
});

server.listen(8888);

There is no request or response object in the scope of your request callback. You need to define them as arguments of the callback function.

var http = require("http");
var server = http.createServer(function(request, response) {
  response.writeHead(200, {
    "content-Type" : "text/html"
  });
  response.end("Hello again");
}).listen(8888);

You should definitely get an error though - are you sure your IDE is set up properly?
