path-dirname 
Node.js path.dirname() ponyfill
This was needed in order to expose path.posix.dirname() on Node.js v0.10
Install
$ npm install --save path-dirname
Usage
const pathDirname = require('path-dirname');
pathDirname('/home/foo');
//=> '/home'
pathDirname('C:\\Users\\foo');
//=> 'C:\\Users'
pathDirname('foo');
//=> '.'
pathDirname('foo/bar');
//=> 'foo'
//Using posix version for consistent output when dealing with glob escape chars
pathDirname.win32('C:\\Users\\foo/\\*bar');
//=> 'C:\\Users\\foo/'
pathDirname.posix('C:\\Users\\foo/\\*bar');
//=> 'C:\\Users\\foo'
