I've tried as much as possible to supply an API that doesn't stray too far from conventions JavaScript programmers are used to from underscore, lo-dash, etc.

This is a nitpick but JavaScript convention is to use camelCase, not underscores, and it feels weird whenever you encounter a library that uses them, usually it's a library that is written by Ruby or Python programmers. It's irritating if it's a library you need to use a lot.
