Learning a more functional language is a good idea, but you can also do more within JavaScript itself. Well after I'd been using higher order functions and Underscore, I found Michael Fogus's Functional JavaScript to be quite good. There is also JavaScript Allongé by Reginald Braithwaite, which I want to read soon. For libraries, there's Lemonad, Bilby and Fantasy Land, all of which push the boundaries of functional programming past what you get from Underscore. Regarding Haskell, I didn't love Learn You a Haskell, but did like Learn Haskell Fast and Hard.
