This project provides a polyfill for the `Set.prototype.difference` method, implementing the ESnext proposal in environments as old as ES3. It's designed for developers who need reliable set operations across all JavaScript environments, particularly older browsers or non-compliant implementations. The shim can

Robustly `.call.bind()` a function
Robust call-bound JavaScript intrinsics, using `call-bind` and `get-intrinsic`.
Define multiple non-enumerable properties at once. Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.
ECMAScript spec abstract operations.
