**Summary:** `is` is a comprehensive JavaScript utility library that provides exhaustive, cross‑environment type‑checking helpers (e.g., `is.array`, `is.number`, `is.promise`, `is.bigint`, etc.) with deprecated aliases for legacy browsers. It is aimed at developers who need reliable, standards‑compliant runtime type validation for writing defensive code, testing inputs, or enforcing contracts in both Node.js and browser environments.
