| ``` |
| |
| **True** |
| |
| ```js |

| isExtglob('@(abc)'); |
| isExtglob('!(abc)'); |
| isExtglob('*(abc)'); |
| isExtglob('+(abc)'); |
| ``` |
| |
| **False** |

| isExtglob('\\!(abc)'); |
| isExtglob('\\*(abc)'); |
| isExtglob('\\+(abc)'); |

| isExtglob('abc/*.js'); |
| isExtglob('abc/(aaa|bbb).js'); |
| isExtglob('abc/[a-z].js'); |
