things have improved a lot over time. I have one project involving json arrays that grew way out of hand. Sort of panicing about the need for a fast 80% rewrite while not having 10% time I tested a good number of devices. Crappy androids and low end iphones deal with the many thousands of objects incredibly fast. I still think its wrong I just have nothing to show for it.

ff a decade ago would just randomly die on me within 2 days.
