/**

Get the real length of a string - by correctly counting astral symbols and ignoring [ansi escape codes](https://github.com/sindresorhus/strip-ansi).
|
||
|
|
|
||
|
|
`String#length` erroneously counts [astral symbols](https://web.archive.org/web/20150721114550/http://www.tlg.uci.edu/~opoudjis/unicode/unicode_astral.html) as two characters.
|
||
|
|
|
||
|
|
@example
|
||
|
|
```
|
||
|
|
import stringLength = require('string-length');
|
||
|
|
|
||
|
|
'🐴'.length;
|
||
|
|
//=> 2
|
||
|
|
|
||
|
|
stringLength('🐴');
|
||
|
|
//=> 1
|
||
|
|
|
||
|
|
stringLength('\u001B[1municorn\u001B[22m');
|
||
|
|
//=> 7
|
||
|
|
```
|
||
|
|

|
||
|
|
declare function stringLength(string: string): number;
|
||
|
|
|
||
|
|
export = stringLength;
