In a “real” rock-paper-scissors game, after each round you want to declare a winner.
For the sake of keeping this demo simple and the source code focused, we do not include

Creating the Game
Our simple application consists of our own HTML and a JavaScript file, and leverages two
external open source JavaScript resources. The first JavaScript library is called stomp.js ,
and was written by Jeff Mesnil. This library is included in the distribution for this topic,
but can also be found on GitHub: https://github.com/jmesnil/stomp-websocket . This
library enables a JavaScript application to speak STOMP/WS with our WebSocket-enabled
ActiveMQ message broker.
The second JavaScript library is jQuery, which we use for simplicity and helps
us write our code in a more concise manner. We call our HTML and JavaScript files
containing our application logic index.html and rps.js , respectively.
