A Promise is a Promise
summary
Explains that deferreds or promises let code attach handlers after resolution and provide a private resolver to signal success or failure; demonstrates synchronization primitives like all/some/any to coordinate many async flows; concrete example runs 100 providers fetching remote data and shows selecting the first N successes; uses wend.js and provides downloadable demos and slides; claims replacement of event-listener hacks with promise/resolver pairs.
