The JavaScript code in core/resources has lots of Doxygen-style comments, but http://svn.mediawiki.org/doc/ displays nothing for it, I assume because it's not PHP.
I hoped this would be as simple as adding .js to FILE_PATTERNS in maintenance/Doxyfile... however I tried this locally and the only documentation it seems to generate for all the resources/*.js files that I checked is
Variables function mw
It may be that mwdoc-filter.php needs to be adjusted for .js files, but it could be that .js files need to be pre-processed, see "For those working with JavaScript..." in http://www.stack.nl/~dimitri/doxygen/helpers.html
