"JavaScript enclosures"?
i think it has to do with encapsulating your code inside a function so
that all vars are inside the function's scope, so not cluttering the
global namespace.
This, to avoid memory leak.
something the likes:
(function(){
/// your code goes here
})(jquery);
I have absolutely no idea if this bits-and-pieces knowledge of mine is
any good, or even if it makes sense :)
