I was actually making an open source sim city clone in JS myself a while ago. Didn't get this far at all, but I was mostly in it to test if I could get async updating from the simulation portion. Essentially doing threading in JS. Which I was somewhat successful in using Web Workers and shared buffer arrays, would be interested in helping with this project. Unfortunately in my research I didn't find any concrete documentation on how the simulation algorithm actually works, so I doubt this would end up a direct clone on SC2K.
