Echo JS 0.11.0

I'm not a mathematician but I'm fairly sure this is only loosely related to category theory. For example, I don't think there is any concept of guarded functions, contracts, etc. in category theory. The video series should probably have been called "Functional Javascript" or something. Excellent videos nonetheless!

You should also read his block to understand what it has to do with category theory: http://jscategory.wordpress.com/. There is also a strong relationship between functional programming and category theory: http://cs.stackexchange.com/questions/3028/is-category-theory-useful-for-learning-functional-programming

Thanks for the links! I didn't realize there was such a strong connection between programming languages and category theory. I just grabbed the book Conceptual Programming to get a better understanding.
