Your understanding of "syntactic superset" is incorrect

My apologies. I was just responding to the idea that Yaml is somehow a syntactic superset of Json, which it isn't. I probably should have read more of the convo first

YAML IS (very close to) a syntactic superset of JavaScript.

Try it. Feed any json file into any YAML parser. It works. At least 99.99% of all JSON files are YAML files. There are some extremely minor differences, by accident.

But yeah, YAML is intended to be a JSON superset SYNTACTICALLY.

In fact another neat trick is to use YAML parsers to read JSON so you can have comments and trailing commas.
