Is this value a JS Boolean? This module works cross-realm/iframe, and despite ES6 @@toStringTag.
|
|
|
|
## Example
|
|
|
|
```js
|
|
var isBoolean = require('is-boolean-object');
|
|
var assert = require('assert');
|
|
|
|
assert.notOk(isBoolean(undefined));
|
|
assert.notOk(isBoolean(null));
|
|
assert.notOk(isBoolean('foo'));
|
|
assert.notOk(isBoolean(function () {}));
|
|
assert.notOk(isBoolean([]));
|
|
assert.notOk(isBoolean({}));
|
|
assert.notOk(isBoolean(/a/g));
|
|
assert.notOk(isBoolean(new RegExp('a', 'g')));
|
|
assert.notOk(isBoolean(new Date()));
|
|
assert.notOk(isBoolean(42));
|
|
assert.notOk(isBoolean(NaN));
|
|
assert.notOk(isBoolean(Infinity));
|
|
|
|
assert.ok(isBoolean(new Boolean(42)));
|
|
assert.ok(isBoolean(false));
|
|
assert.ok(isBoolean(Object(false)));
|
|
assert.ok(isBoolean(true));
|
|
assert.ok(isBoolean(Object(true)));
|
|
```
|
|
|
|
