seroval is a tiny JavaScript library that converts any JavaScript value—including primitives, objects, arrays, Maps, Sets, Dates, RegExps, BigInts, `undefined`, `NaN`, `Infinity`, and even complex cyclic or mutually‑referencing structures—into a self‑executing string representation that can be `eval`‑ed to recreate the original data. It’s aimed at developers who need a reliable, dependency‑free way to serialize rich JavaScript data (e.g., for storage, caching, or transport) while preserving reference integrity across environments.
