I highly recommend "Functional JavaScript" by Michael Fogus (creator of Lemonad), http://www.amazon.com/Functional-JavaScript-Introducing-Prog...

It will arrive to my door this Friday, really excited to read it!

Concerning lemonad, since there's no documentation yet, I think the Annotation is really the way to go to get a quick feel at what the library has to offer: http://fogus.github.io/lemonad/lemonad.html

And the test specs as well http://fogus.github.io/lemonad/test.html

Another great project:

Bilby: Serious functional programming library for JavaScript https://github.com/puffnfresh/bilby.js

Thanks for posting that. I'm quite impressed by what's in there, especially the bit of cleverness involved with the bilby.Do() syntax.

Lemonad was once much larger with a wider range of functional operators. Recently most of its functions have been moved into underscore-contrib (https://github.com/documentcloud/underscore-contrib). Most of my JS time lately has been spent with _.contrib, but I plan to come back to Lemonad soon and write up full docs and the like.

http://fogus.github.io/lemonad/lemonad.html#section-21 - nice breaking bad reference http://www.imdb.com/title/tt0903747/

Also lemonad is french for monad.

All these functions -with better docs- already exist in NPM.

Care to elaborate, or provide a link?
