What Node.js taught me is that JavaScript is language like any other. It has good parts, it has quirks and you have to know what are its strenghts and what are its weaknesses to use it properly. And you can say that about any other language.
Does what you just said mean that we shouldn't talk about JS's weaknesses?
Or do you mean that we can, but that the points the author brings up have been beaten to death time and time again here on HN and this post + the inevitable comments it will attract have nothing to offer?
Those are the only two options I can think of for now. Or did you mean something else?
There are many totally lucid, on-point criticisms of Javascript and at least once a day the language ticks me off, but this one is not so black-and-white.
