Unity’s javascript is not real javascript. Unity’s javascript is a different language called UnityScript, whose syntax is similar to original javascript.

UnityScript is based on Mono, a open source .Net framework implementation. so what you need is .Net socket, not socket.io.

http://msdn.microsoft.com/en-us/library/system.net.sockets.tcpclient.aspx

For example, to create a TCP client socket in C#:

TcpClient client = new TcpClient(server, port);
NetworkStream stream = client.GetStream();
stream.Write(data, 0, data.Length);

In UnityScript:

var client : TcpClient = new TcpClient(server, port);
var stream : NetworkStream = client.GetStream();
stream.Write(data, 0, data.Length);

Different syntax, but the same API/library.
