Gone through code as below couldnt understand the working of code 1...what is the difference between the two codes below

**

What is the point of using http and express togather in code 1?

Code1

var app = require('express')();
var http = require('http').Server(app);

app.get('/', function(req, res)
{
   res.sendFile(__dirname+'/index.html');
});

http.listen(3000, function()
{
  console.log('listening on *:3000');
});

The same thing can be done as

Code2

var express=require('express');

var app=express();

var socket=require('socket.io');

app.get('/',function(req,res){
    res.sendFile(__dirname+'/index.html');

}).listen(8080);
console.log("Listening to port 8080");

The app object conventionally denotes the Express application which is created by top level express() function exported by the Express module.

http.listen(): Starts the HTTP server listening for connection

In the second case it works app.listen() which binds and listens for connection on the specified port and it identical to http.listen()

You're asking about the difference of expressjs own server and http server. They are different in many ways.
