I would add 'unforgiving use of linters' to that, where 'unforgiving' generally means that straying even a hair's breadth from the default settings is forbidden. Especially so when you can't adjust those defaults, thus making your post-listed code substantially more abstract and less readable than it would have been at first. Case in point: forcing your simple 11-line function to become something more complicated that has to maintain state through each call.
