Sample
parse and stringify JSON5 with comments, trailing commas, and unquoted keys

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
- JSON5.parse parses objects with unquoted keys, single-quoted keys, and trailing commas
- JSON5.parse ignores single-line and multi-line comments
- JSON5.parse parses hexadecimal numbers, leading/trailing decimals, explicit plus signs, Infinity, and NaN
- JSON5.parse supports single-quoted strings with line continuations and escape sequences
- JSON5.parse accepts an optional reviver function to transform parsed key-value pairs
- JSON5.stringify serializes objects with unquoted identifier keys and configurable quote formatting
- JSON5.stringify preserves Infinity, -Infinity, and NaN as identifiers rather than null
- JSON5.stringify accepts a replacer function or array and custom space indentation
- JSON5.parse throws SyntaxError on invalid JSON5 input syntax
