Redirect skin.js
Language(s):	JavaScript
Compatible with:	MediaWiki 1.17+ (Vector; Monobook)

Description

Redirect User:Name/skin.js and skin.css to the current skin's pages (unless the 'skin' page really exists).

It probably makes more sense to encourage people to just use Special:MyPage/common.js and Special:MyPage/common.css instead of redirecting /skin.js. See also phab:T71555.

Code

The below snippet uses the mediawiki.util module. Either add that module to the list of dependencies or, wrap it in:
mw.loader.using( 'mediawiki.util', function () { .. } );

/**
