Implementations

node.js and some browsers have Promise built-in. Since all of these are Promise/A+, they are all used the same way.

• http://bluebirdjs.com/ - optimized for speed
• https://github.com/tildeio/rsvp.js - optimized for byte size, used by Ember

Don't use these; there's really no point. But these were relevant in the past:

• https://github.com/kriskowal/q
• https://github.com/dfilatov/vow
• https://api.jquery.com/deferred.promise/ - avoid like the plague, not Promise/A+ compatible

async functions
