I .promise() to show you .when() to use Deferreds
summary
Demonstrates seven concrete patterns using jQuery Deferreds: bundling three parallel Ajax sources with when to render a sidebar, storing a Deferred on page objects so some pages wait for data while others resolve immediately, a 10-line caching trick that saves a round trip by reusing a resolved Deferred, wrapping setTimeout as a Deferred-based wait, combining many animations with when.apply to return one Deferred, and using notify progress plus resolve/reject to track long tasks; code examples show these patterns working in practice.
