        JSON maps to a small set of nearly universal types and data structures. It is intuitive to write, read and reason about. XML is not.

        List, map, number, string, boolean, null. What else do you need? Maps nicely to pretty much every language -- thus massive adoption.

        map: ordered or unordered? How do you deal with dup keys: { "//": "fake comment", "//": "really exists" }

        every one of these questions has personally cost me dozens of hours and didn't result in a satisfactory results.

        DOZENS of hours? You have had to slog through some pretty poor JSON APIs. I can't say I've ever had to even care.

        1. XML has an infoset, and JSON does not. This makes JSON simpler. 2. JSON has dicts, XML has attributes. 3. XML requires encodings.

        I assume (2) is meant to be a wash?

        yes, but see 3. No one has to encode attributes in JSON.

        I think you're cheating quite a bit re JSON. Recall that the JSON spec intentionally elides semantics, therefore no infoset.

        the semantics of json are charitably the JSON section OF ECMA262 (not small) and in practice lots of encoding/number incompat

        XML doesn't have number issues because it doesn't have numbers. It's simpler in that respect, but not in syntax or usability.

        I think of GraphQL as more like SQL than JSON but I get what you're getting at.
