     25 <section class="usage">
     26 
     27 ## Usage
     28 
     29 ```javascript
     30 var reExtname = require( '@stdlib/regexp/extname' );
     31 ```
     32 
     33 #### reExtname( \[platform] )
     34 
     35 Returns a [regular expression][regexp] to capture a filename extension.
     36 
     37 ```javascript
     38 var RE = reExtname();
     39 // returns <RegExp>
     40 
     41 RE = reExtname( 'posix' );
     42 // returns <RegExp>
     43 
     44 var ext = RE.exec( '/foo/bar/index.js' )[ 1 ];
     45 // returns '.js'
     46 
     47 RE = reExtname( 'win32' );
     48 // returns <RegExp>
     49 
     50 ext = RE.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
     51 // returns '.js'
     52 ```
     53 
     54 #### reExtname.REGEXP
     55 
     56 [Regular expression][regexp] to capture a filename extension.
     57 
     58 ```javascript
     59 var bool = ( reExtname.REGEXP.toString() === reExtname().toString() );
     60 // returns true
     61 ```
     62 
     63 #### reExtname.REGEXP_POSIX
     64 
     65 [Regular expression][@stdlib/regexp/extname-posix] to capture a [POSIX][posix] filename extension.
     66 
     67 ```javascript
     68 var ext = reExtname.REGEXP_POSIX.exec( '/foo/bar/index.js' )[ 1 ];
     69 // returns '.js'
     70 ```
     71 
     72 #### reExtname.REGEXP_WIN32
     73 
     74 [Regular expression][@stdlib/regexp/extname-windows] to capture a Windows filename extension.
     75 
     76 ```javascript
     77 var ext = reExtname.REGEXP_WIN32.exec( 'C:\\foo\\bar\\index.js' )[ 1 ];
     78 // returns '.js'
     79 ```

     87 ## Notes
     88 
     89 -   The as `REGEXP` exported [regular expression][regexp] is [platform][@stdlib/assert/is-windows]-dependent. If the current process is running on Windows, `REGEXP === REGEXP_WIN32`; otherwise, `REGEXP === REGEXP_POSIX`.
