The amount of code matters when the lowest-performing Androids on the market have an order of magnitude less single core performance than a modern iOS device. V8 parse times have got much better over the last few years (they used to be a big bottleneck) but you’ve still got major execution cost leading to bad user experience.

The code size is a poor proxy for performance though. React likely has some areas which are much more performant just because of development efforts, even if it's larger. If we want performance, that's the metric that should be public and clear.

FWIW, VanJS's performance is very impressive. At least much better than React: https://vanjs.org/#performance
