I recently worked on two different projects that involved a fair amount of Javascript centering around using the Google Maps API. In doing so I began to factor out some of the components to be reusable in a general Google Maps project. While I usually use the excellent Prototype Javascript library I didn't want to leak Prototype code into these reusable components. This led me to using these functions, borrowed / evolved from various places, as the core functions to support the components:
I think these functions are a pretty good representation of the baseline support you will want in many Javascript projects.
