Hmm -- there's no indication for the author not understanding the patterns. The point is, JS does not need these patterns (which are usually imported concepts from other languages), there are unique ways to do it in JS. (Think of late binding.) The critique is, JS is becoming that enterpisey like backends used to be at the time of the dot-com-bubble. It's the framework bubble.

Developers have become used to loading several K lines of code, just to remote control quite simple tasks, that could have been done natively by a humble number of lines of code. It's high time to point out that there isn't any emperor inside the new cloths! (Just a bunch of woven code.)
