17```js
18var isRegex = require('is-regex');
19var assert = require('assert');
20
21assert.notOk(isRegex(undefined));
22assert.notOk(isRegex(null));
23assert.notOk(isRegex(false));
24assert.notOk(isRegex(true));
25assert.notOk(isRegex(42));
26assert.notOk(isRegex('foo'));
27assert.notOk(isRegex(function () {}));
28assert.notOk(isRegex([]));
29assert.notOk(isRegex({}));
30
31assert.ok(isRegex(/a/g));
32assert.ok(isRegex(new RegExp('a', 'g')));
