You need to explain more - for example what do you mean by a "partial"? A quick search for "partial functions" gave me several links to mathematics articles. When I followed the links to the composition modules I got more of the same impenetrable context-less style.
What I did get from the article is something that works a lot like promises:
- async functions return type of "eventual" data (in your case, a function you pass a callback to)
- various other functions that can operate on that eventual data type to return more eventual data
What does this style offer that standard promises doesn't?

The magic phrase you were looking for is "partial application." (Partial functions are a different, even more esoteric thing.) Basically, partially applying a function means you create a new function that calls the original with some of the arguments already filled in. For example, you could write this:
var getUserList = partiallyApply(jQuery.getJSON, 'http://example.com/user-list');
and getUserList would then be a function that takes a callback and calls
I believe that using basic functional programming tools is a much more powerful way than using promises. The main issue with promises is that the code you write will be less replaceable, and less compatible with other code.
