If I see a cool effect on a website I view the source of jquery and usually I can wrap my head around it ,however, I was looking at the slider for http://www.mckinsey.com and viewed the jQuery source that is used in doing the page slide: http://www.mckinsey.com/assets/dotcom/js/home.js

I can’t seem to understand how this jQuery code is written or what it does, though, I do understand that it is written in a better fashion and can be maintained properly since everything is not inside the document.ready() function

  • Can someone break this code down a little to explain (I’m just concerned with slider not, not cookies)

  • Are there tutorials/books that show how to write/understand jQuery code written in this manner.
