"Fast" is good. "Clojure(Script)" lets me know I can use it on the browser side. "Data-driven" is useless, it is not telling me anything in a homoiconic environment where code is data and data is code.
If it wasn't data driven and I needed it I would write just one probably small macro and be able to translate a data structure to the right calls and get the same effect.
What you would have to do to make a non-data-driven API data-driven is the work you are saved from having to do by having the API already data-driven.
It is neither good nor bad. In the end it's another API you need to learn if you choose to use it.
