I have somehow settled into the pattern of using new/java-like classes for large objects that store a logical set of data and need to operate on it, and on-the-fly prototypes to groups group just data (or, perhaps, a trivial operation). My worst crime by far (that I am aware of) is that I have no hesitation to use a global variable if it saves me from bending over backwards to get around it. I'm doing animations, and sometimes the algorithm just comes to me a lot faster if I let a var keep a global value and be used by lots of functions between calls to my animate() function (using window.setInterval() ).
