snippet::is-weakmap

Simple or drop-in replacement

This package is no longer necessary. You can use `instanceof WeakMap` to check if a value is a `WeakMap`, or if cross-realm, use `Object.prototype.toString.call(v) === "[object WeakMap]"`

// example

const isWeakMap = v instanceof WeakMap;
// for cross-realm
const isWeakMapCrossRealm =
	Object.prototype.toString.call(v) ===
	'[object WeakMap]';
