@email@example.com Have you worked on an engineering team with really great programmers new to the language you are maintaining? I ask because actually I prefer several of the the anti-patterns in the essay for the sake of either inten-revealing simplicity (in the case of isOdd, although why use NPM when you could create the function in two lines?) or propagating errors to the front end (in the case of the HTTP response codes).
