I am new to javascript and I would like to specify a javascript program to read from a file and print the contents of the file to a console?.This is the code I have written below and am getting an error,please what's wrong with it?

var express = require('express');

var app = express.createServer(express.logger());

app.get('/',function(request,response){

     var fs = require('fs');
     var buffer = new Buffer(fs.readFileSync('index.html','utf8'));

         response.send(Buffer.toString());

});

   var port = process.env.PORT || 5000;
   app.listen(port,function()
{
    fs.readFileSync();
    console.log("Listening on"+ port);
}
);

Use the readFile method of the fs object to read the file, then use console.log to print it:

/* File System Object */
var fs = require('fs');

/* Read File */
fs.readFile('foo.json', bar)

function bar (err, data)
  {
  /* If an error exists, show it, otherwise show the file */
  err ? Function("error","throw error")(err) : console.log(JSON.stringify(data) );
  };

For instance, if it is named loadfiles.js, run it as such:

node loadfiles.js
