The 'Promise' term in JavaScript represents the result of a task, which may or may not have completed yet. It basically refers to what to expect for a JavaScript AJAX call.
Promises/A+ is an unofficial open standard for helping and showing developers on how to deal with promise calls.
RSVP.js is a simple JS library that implements some of these concepts in JavaScript and allows AJAX developers to write applications modeled around this code behavioral pattern.
Works with client-side (browsers) and server-side (Node.js) environments.
RSVP.js is also compatible with Task.js.
