|

|
| 16 | var ansiRegex = require('ansi-regex');
|
| 17 |
|
| 18 | ansiRegex().test('\u001b[4mcake\u001b[0m');
|
| 19 | //=> true
|
| 20 |
|
| 21 | ansiRegex().test('cake');
|
| 22 | //=> false
|
| 23 |
|
| 24 | '\u001b[4mcake\u001b[0m'.match(ansiRegex());
|

|
| 26 | ```

|
| 28 | *It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*
