Awesome Promises
A curated list of useful resources for JavaScript Promises
Inspired by the awesome list thing. Not to be confused with other awesome promises like "I promise you a million dollars" or "I promise you'll stay fit and never have to go to the gym again".

Promises/A+ Implementations (ES6/ES2015 compatible)
Strict Implementations
These implement no more or less than the es6 spec. They make great polyfills and are exceptionally compatible with native promises.
- pinkie - Ponyfill. Node-oriented, but browserifyable. Extremely small implementation.
- native-promise-only - Polyfill. Browser and node-compatible.
- es6-promise - Opt-in polyfill. A strict-spec subset of rsvp.js.
- lie - Small, browserifyable with an opt-in polyfill.
Implementations with extras
All of these provide more features than the language yet remain compatible. Node + Browsers for all.
