What is nodejs-q
Q is a tool for making and composing asynchronous promises in JavaScript. If a function cannot return a value or throw an exception without blocking, it can return a promise instead.

A promise can also be used as a proxy for a remote object to overcome latency. Q can exchange promises with jQuery, Dojo, When.js, WinJS, and more.
