- 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
- Simply clone the repo, `npm install`, and run `npm test`
