Cannot run ch11-code #137

This is the first time I read this book, so I would like to read and run some example as soon as possible to see how functional programming would help me. However, after pulled the code, I opened ch11-code and and ran it, I always got this error: 

Uncaught TypeError: Function.prototype.apply was called on #<HTMLUListElement>, which is a object and not a function
    at a.partiallyApplied [as _next] (fp-helpers.js:48)

I'm using Chrome version 62.0 to run this example.

Thanks for finding this bug. I introduced it in a recent tweak to the code. Fixed now. :)
