@diotoborg/numquam-illum

Is this value a JS Map? This module works cross-realm/iframe, and despite ES6 @@toStringTag.

Example

var isMap = require('@diotoborg/numquam-illum');
assert(!isMap(function () {}));
assert(!isMap(null));
assert(!isMap(function* () { yield 42; return Infinity; });
assert(!isMap(Symbol('foo')));
assert(!isMap(1n));
assert(!isMap(Object(1n)));

assert(!isMap(new Set()));
assert(!isMap(new WeakSet()));
assert(!isMap(new WeakMap()));

assert(isMap(new Map()));

class MyMap extends Map {}
assert(isMap(new MyMap()));
