      Also, can we just talk about vdom overhead for a minute? I'm grateful the marketing dreck about it being "faster" quietly exited stage left

      But we need to all admit that doubling up your data structures & doing work O(num-elements) when changes are smaller is *not fast*

      +1. This was exactly the reason for once - DOM diffing without any intermediate data structureshttps://github.com/utilise/once

      "DOM is slow" was hugely misleading. DOM is not slow to walk, or read. Updates may be slow. Vdom is just buzzword for memoization.

      That benchmark has been broken for a long time. It's extremely easy to "cheat", just like most benchmarks are.

      I don't disagree, but this standard was presented React conf, trashed angular/ember on stage. Now it's broken? Which benchmark is better?

      Nowadays, the performance of all the popular js frameworks is acceptable and it's no longer the main driver to go see somewhere else.

          Caveat emptor: I'm primarily focused on mobile; what you say may be true on desktop (but I see traces that give me pause there too).

          I'm talking about what people report to me. I don't see a massive uprising of React users because of perf like I've seen with Angular.
