This is in CoffeeScript rather than JavaScript, but hopefully it should be clear. In our app we typically have to load multiple things before rendering a page. Using jQuery's Deferred objects the pattern is very simple. This is probably the most basic example we use. I've got some more interesting cases as well, such as fetching many records in …
