FWIW, the time spent in JS is only telling half the story. In that first example, React spends half as much time painting and rendering as Vue; the DOM diffing is more js-time intensive but results in less DOM thrashing. Interesting to watch how poorly it seems to scale; I'm wondering if web workers in future React versions will change that story.

In case you missed it, the author confirmed the tests were accidentally using the development version of React, which is significantly slower due to the additional warnings and sanity checks. The actual results seem to be much less surprising.
