The `is-map` module is a utility for determining if a given value is a JavaScript Map object, including those created across different realms or iframes. It is designed for developers working with JavaScript who need a reliable way to check for Map instances, even when dealing with complex scenarios involving inheritance or ES6 `@@toStringTag`.
