Stuart told me it would be awesome if websites could work on mobile just as well as on desktop. For JS, this basically means performance. I'm not sure yet how to think about time and space tradeoffs, but for now maybe we can think of it as how much speed we can get with an acceptable space cost. There are 3 main questions here: 1. What is the current state of JS perf on mobile ARM devices compared to desktop? 2. How close can we get JS perf on ARM to desktop? 3. What do we have to do to get that close?
