This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- parseJson parses valid JSON text into JavaScript values
- parseJson transforms parsed values when given a custom reviver function
- parseJson strips leading UTF-8 byte-order mark before parsing
- parseJson attaches indentation and newline metadata symbols to objects and arrays
- parseJson throws JSONParseError subclassing SyntaxError on invalid JSON
- parseJson formats error message with context snippet when parsing truncated JSON
- parseJson.noExceptions returns undefined for invalid JSON and parsed value for valid JSON
- parseJson throws TypeError with code EJSONPARSE for non-string non-buffer input that cannot be parsed
