An introduction to functional programming in JavaScript

Wow thanks. That is a lot of information. (31 screens deep. 29 without images, 17 with no images and no gists) I think this needs to be bookmarked and re-read several times for me to wrap my head around it.

I Have to something to ask after my first skim-though. If mutability & state are such bad ideas. Why are so many using them?

I'm aware there are situations where mutability is bad. Accidentally transforming the value of a users e-commerce cart could be bad for example. I'm just not sure the hard-line strict purity is practical for a broader system. I'd be happy to hear my initial feelings are incorrect, but would appreciate some links.
