You know that jQuery is primarily a "wrapper around the DOM API", right?
Yes, that's the definition of a wrapper: it offers it's own API.
This library is a list of functions that are nothing but proxies for some other functions which you might as well call directly. Given that the author has written this http://zedshaw.com/essays/indirection_is_not_abstraction.htm... I am sure this is some kind of joke...
That's the whole point of making a wrapper around an API. That it doesn't look like the API you're wrapping.
