I would ask : What is the benefit of operations.js vs promises?

Similar to the examples you can easily do :

    promiseA.then(promiseB).done( ... )

[mtford → drinchev]

Yeah, operations.js is meant for more complex scenarios than that. For example if we were spawning hundreds of operations that interact with networks/file systems. We can set an upper limit on concurrent operations using queues and express complex dependencies between them, compose them and cancel them.

I don't see any new features that wouldn't be possible in async. Am I missing something ?

Hi Luna, from my perspective async.js is about control flow whereas operations.js is about creating well defined operations that can be composed, queued, cancelled, reused and monitored. It's more of a workhorse.
