Node.js tcp client and server example

nodejs-tcp-example.js

/*
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp 
server, but for some reason omit a client connecting to it.  I added an 
example at the bottom.

Save the following server in example.js:
*/

var net = require('net');

var server = net.createServer(function(socket) {
	socket.write('Echo server\r\n');
	socket.pipe(socket);
});

server.listen(1337, '127.0.0.1');

/*
And connect with a tcp client from the command line using netcat, the *nix 
utility for reading and writing across tcp/udp network connections.  I've only 
used it for debugging myself.

$ netcat 127.0.0.1 1337

You should see:
> Echo server

*/

/* Or use this example tcp client written in node.js.  (Originated with 
example code from 
http://www.hacksparrow.com/tcp-socket-programming-in-node-js.html.) */

var net = require('net');

var client = new net.Socket();
client.connect(1337, '127.0.0.1', function() {
	console.log('Connected');
	client.write('Hello, server! Love, Client.');
});

client.on('data', function(data) {
	console.log('Received: ' + data);
	client.destroy(); // kill client after server's response
});

client.on('close', function() {
	console.log('Connection closed');
});

Can you please give me an example of code about how to use the client in HTML file with Java Scripting?
Thanks!
