Is this value a JS Map? This module works cross-realm/iframe, and despite ES6 @@toStringTag.
|
|
|
|
## Example
|
|
|
|
```js
|
|
var isSet = require('is-set');
|
|
assert(!isSet(function () {}));
|
|
assert(!isSet(null));
|
|
assert(!isSet(function* () { yield 42; return Infinity; });
|
|
assert(!isSet(Symbol('foo')));
|
|
assert(!isSet(1n));
|
|
assert(!isSet(Object(1n)));
|
|
|
|
assert(!isSet(new Map()));
|
|
assert(!isSet(new WeakSet()));
|
|
assert(!isSet(new WeakMap()));
|
|
|
|
assert(isSet(new Set()));
|
|
|
|
class MySet extends Set {}
|
|
assert(isSet(new MySet()));
|
|
```
|
|
|
|
