The **var‑clean** package is a tiny Node.js utility that sanitises primitive values according to a strict type‑cleaning specification. It provides two APIs – `clean` (which returns the cleaned value or `undefined` when the input cannot be coerced) and `cleanOrThrow` (which throws a descriptive error for invalid inputs) – and supports booleans, truthy/falsy checks, integers (including positive‑only), and string conversion. It’s aimed at developers who need reliable runtime validation and normalization of simple JavaScript values.
