snippet::is-map

Simple or drop-in replacement

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

// example

const isMap = v instanceof Map;
// for cross-realm
const isMapCrossRealm =
	Object.prototype.toString.call(v) ===
	'[object Map]';
