Warning perhaps this is a dumb question. I naively would have thought that storing DOM references (in this case, in object properties because our scripts are object-oriented) would improve performance, eliminating needless lookups. However, now I wonder if doing so taxes browser memory, particularly in IE, and slows down a web application as more and more DOM object references are stored in object properties. I'm basically unclear on the entire issue. Could anyone shed some light on this topic?
