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'))); |
|
``` |
|
|
|
