I read this. I read it if only to glean why anyone would do this. I learned nothing of the sort of person who would use Javascript to structure a YAML config.

I read this. I read it if only to glean why anyone would do this. I learned nothing of the sort of person who would use Javascript to structure a YAML config. 10 years ago this article would have been "Used PHP for structured YAML config" and there would have been a minor riot of people poking fun at the article writer for attempting such sillyness. (And I say this someone who still made my money on PHP 10 years ago). We got soft somewhere along the way and stopped calling out silliness.
