SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server.

The remainder discusses Socket.io, an abstraction layer that allows real-time applications to work across WebSocke
