Vow

The 'Promise' term in JavaScript was coined with the emergence of server-side JavaScript development.

It basically represents the result of a task, which may or may not have completed yet. Or in simpler words, what to expect for a JS call.

Promises/A+ is simply an open standard detailing how to deal with promises.

The Vow library simply ports most of the principles to JavaScript, alllowing developers to use it with client-side (browsers) and server-side (Node.js) environments.
