`which-collection` is a JavaScript utility library that identifies whether a given value is a `Map`, `Set`, `WeakMap`, or `WeakSet`, returning `false` for all other types. It's designed to work cross-realm and without relying on `instanceof` or `Symbol.toStringTag`, making it reliable for complex JavaScript environments. This tool is ideal for developers working with JavaScript collections who need robust type detection in cross-realm scenarios.
