As it says on the site, Fogus is "a core contributor to Clojure and ClojureScript". I wonder why he didn't just write a book on ClojureScript instead. Isn't ClojureScript already a way to write functional javascript?
So far I've been disappointed by the "functional X" books.. Probably because I've read SICP and much of the "functional" books just repeat the same patterns over and over.. i.e. memoization, closures, map, reduce, etc. Still, I'm a sucker for these books and I'll gladly buy it. Hopefully I'll learn a thing or two.. and if I do so, I'll be more then happy to share the word about it! : )
The otherwise beautiful 'official site' has a very curious 'feature' right at the bottom: a glossary of choice words which, on click, pop open a window alert with their 'definition'. It gets even more bizarre: at least two of those items return "glossary entry for [xyz] not yet available".
