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
- Parsing valid JSON returns the parsed JavaScript value.
- Parsing valid JSON with a custom reviver function transforms values according to the reviver.
- Passing a filename string as the second argument parses valid JSON successfully.
- Passing both reviver and filename arguments parses valid JSON successfully.
- Parsing invalid JSON throws an instance of parseJson.JSONError.
- Passing a filename as the second argument attaches fileName and appends 'in <filename>' to the error message.
- Passing reviver and filename attaches fileName and appends 'in <filename>' to the error message.
- Mutating the fileName property on a caught JSONError updates the fileName property and the formatted error message.
