Yeah. I mean...

First off, the attraction of React, to me, is mostly based on being able to write maintainable, testable, reusable, easy to reason about code when working on large, complex webapps. Yeah, React has relatively high performance—at least when compared to a sluggish framework like Angular when writing those large apps, but that's not even the core selling point (as far as I'm concerned). But okay, part of the attraction of React could be summed up as "better performance than Angular on complex applications", and I guess a benchmark proving (or disproving) that would be nice to have.

That's not what we got. Instead, this guy tested the raw performance of some very simple code compared the sort of vanilla code you'd never ever ever write in the sort of app that React (or Angular) is actually designed to help with. So...yes, React is slower than vanilla JS at stuff that vanilla JS is faster at. Shocking.

I'm struggling to think of a less meaningful way to do the analysis.

Said every developer who's never had to "just speed up" an application written with a framework that makes development/debugging easy, but has fundamental performance issues that cannot be overcome without a significant overhaul.
