Can you point me to a language with any significant number of users that does NOT have a JSON library?
I went looking at some of the more niche languages like Prolog, COBOL, RPG, APL, Eiffel, Maple, MATLAB, tcl, and a few others. All of these and more had JSON libraries (most had one baked into the standard library).
The exceptions I found (though I didn't look too far) were: Bash (use jq with it), J (an APL variant), Scratch (not exposed to users, but scratch code itself is encoded in JSON), and Forth (I could find implementations, but it's very hard to pin down forth dialects).
