Here's a great explanation of a) what promises are and b) how the promises/deferreds code in the $.ajax method is being refactored out for general use: http://blog.rebeccamurphey.com/deferreds-coming-to-jquery

> jQuery is using promises, and not futures.

Can anyone explain the difference between promises and futures? I've always used the terms interchangeably.

My understanding is that a future's value is supplied by the function it is created with (which is evaluated in a background thread), whilst a promise's value is delivered by another thread. Both constructs will block if accessed before their value is resolved.

This seems to me an implementation detail, are there any observable differences?
