> Returns true if a string has an extglob.
## Install
Install with [npm](https://www.npmjs.com/):
```sh$ npm install --save is-extglob```
## Usage
```jsvar isExtglob = require('is-extglob');```
**True**
```jsisExtglob('?(abc)');isExtglob('@(abc)');isExtglob('!(abc)');isExtglob('*(abc)');isExtglob('+(abc)');```
**False**
Escaped extglobs:
```jsisExtglob('\\?(abc)');isExtglob('\\@(abc)');isExtglob('\\!(abc)');isExtglob('\\*(abc)');isExtglob('\\+(abc)');```
Everything else...
```jsisExtglob('foo.js');isExtglob('!foo.js');isExtglob('*.js');isExtglob('**/abc.js');isExtglob('abc/*.js');isExtglob('abc/(aaa|bbb).js');isExtglob('abc/[a-z].js');isExtglob('abc/{a,b}.js');isExtglob('abc/?.js');isExtglob('abc.js');isExtglob('abc/def/ghi.js');```
## History
**v2.0**
Adds support for escaping. Escaped exglobs no longer return true.
