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