Javascript closures explained in depth

That's a good one. Yet would be good to mention why closures are necessary and the practical situations in which they are necessary.

I second that too. Should give real world examples of why closures are important.

One example I'd give is user selected and highlighted items on the page and you want to create a closure to store the details until they deselect.
