For some context: 54 clients.each(function(c) { 55 if (c != client) 56 c.connection.send(client.name + ": " + data); 57 }); Line 55 is just there as a check to prevent echoing back the message to the client that sent it (as presumably the message they type will already be on their screen/terminal, if they are connected with netcat as the author suggests).
