The behind the scenes writeup is good: http://www.cuttherope.ie/dev/ Although the senior developer says in the video: "Objective C is object oriented, has classes and structs. And those things just don't exist in JavaScript." .. Well, except object orientation, of course ;-)
Are you saying that you think Javascript is object oriented because it can create an Object and enclosed functions? I have always been taught while we can make it look like OOP, it is not because it does not have inheritance through classes AS PART OF THE LANGUAGE.
