+Which kind of Collection (Map, Set, WeakMap, WeakSet) is this JavaScript value? Works cross-realm, without `instanceof`, and despite Symbol.toStringTag.
+
+## Example
+
+```js
+var whichCollection = require('which-collection');
+var assert = require('assert');
+
+assert.equal(false, whichCollection(undefined));
+assert.equal(false, whichCollection(null));
+assert.equal(false, whichCollection(false));
+assert.equal(false, whichCollection(true));
+assert.equal(false, whichCollection([]));
+assert.equal(false, whichCollection({}));
+assert.equal(false, whichCollection(/a/g));
+assert.equal(false, whichCollection(new RegExp('a', 'g')));
+assert.equal(false, whichCollection(new Date()));
+assert.equal(false, whichCollection(42));
+assert.equal(false, whichCollection(NaN));
+assert.equal(false, whichCollection(Infinity));
+assert.equal(false, whichCollection(new Number(42)));
+assert.equal(false, whichCollection(42n));
+assert.equal(false, whichCollection(Object(42n)));
+assert.equal(false, whichCollection('foo'));
+assert.equal(false, whichCollection(Object('foo')));
+assert.equal(false, whichCollection(function () {}));
+assert.equal(false, whichCollection(function* () {}));
+assert.equal(false, whichCollection(x => x * x));
+assert.equal(false, whichCollection([]));
+
+assert.equal('Map', whichCollection(new Map()));
+assert.equal('Set', whichCollection(new Set()));
+assert.equal('WeakMap', whichCollection(new WeakMap()));
+assert.equal('WeakSet', whichCollection(new WeakSet()));
+```
