json‑literal is a Node.js library that extends JSON with additional literal types—Date, RegExp, null, undefined, octal numbers, and circular references—while also allowing unquoted keys, single‑quoted strings and comments. It provides a safe `parse` (no eval) and a matching `stringify` that produces a more human‑readable representation, useful for developers who need to serialize/deserialize JavaScript objects that contain these richer constructs.
