He obviously went and reviewed the rest, or how would he know about the uWebsockets portion? His point is that the article is poorly written enough that he had no desire to finish it, and I fully agree. More information and less disparaging fluff would make this piece much more attractive to the engineers of the world.
In fact I gave up around the insults at various Express-successors, and missed that the main point of the article is the µWebSockets.js.
Why not go into that directly and skip the rest? That's what people would want to know, not that "Node is worse than Golang in raw performance".
