Yes, it's an admirable design. I've used it. I know. And no, nothing I've done with it has been intolerably slow. Although now I'm starting to wonder about some responsiveness issues I've experienced...

I also wonder if batteries care about elegance. Not really they don't. If one makes the highly likely assumption that these micro benchmarks are a measure of efficiency then it's actually difficult to do worse than React regarding battery life, heat, etc.

Very interesting.
