We're using jQuery on a less UI-intensive project whereas we have been using ExtJS on other projects. Regardless, I'm curious if any of the prevalent libraries such as ExtJS, jQuery, or others, provide a utility for "pruning" objects? By which I mean, deleting keys if they don't contain values. I've devised my own (naive) implementati...
(I know what null is and what its is used for) Question: OK, say we make a reference to an object in whatever language. The computer makes a little 32-bit (or other size, depending on computer's design) space in memory for that reference.

I'm not sure really how to ask that question.. hopefully my explanation will clarify: I have a public method in a class, say Widget that takes a list of Widgets and makes changes to them.

Bill Karwin has a blog post called "Why Should You Use An ORM?" which is being discussed on Reddit and I was confused about a couple of points. In it he says in the comments section: OODBMS and ORM works only on objects that we've instantiated in the application layer. I.e. there's no way to do a query like this: UPDATE B...
