In any reasonable language, it would first alert "Hello", and then alert "World". But noooo. Javascript's gotta get all fancy and defer execution until later. And at that point message is equal to "World" for both. So it's "World" "World", which ain't right at all.

I voted up because the article opens the discussion of the behavior of anonymous functions, which can be counter-intuitive if you are used to other languages.

JavaScript didn't defer execution, the author did by putting the calls to the functions at the end.
He's apparently confused that the global variable 'message' is.... global.
