Library json
Library methods for handling JSON data. It handles JSON encoding and decoding according to RFC 4627.
There is a test section at the bottom which shows some example
parsing. If you want to parse JSON, you can test it by pasting sample JSON
into the TESTS table and run the test method
There is a straightforward mapping between JSON and Lua data types. One
exception is JSON NULL, which is not the same as Lua
nil. (A better match for Lua nil is JavaScript
undefined.) NULL values in JSON are represented by
the special value json.NULL.
