I suppose it could be considered more 'general' programming advice, not specific to JS. At least here on HN there seems to be a consensus that classical inheritance more than 1 layer deep is a bad idea (correct me if I'm wrong though, dear HN readers and writers!).

Personally I'm a huge functional programming weenie for no reason I can coherently defend, so I prefer to avoid ES6 classes. But quite often they end up being the most reasonable solution to my problem, and having syntax for it is great. I just avoid them by default.
