I only had it officially support .pde files.

I don't think the language files for the extension support processing.js - I suppose a psj can still be useful having just the java highlighted.

I don't work in processing.js, just for laughs could you rename the file to .pde, and see how the syntax highlighting works? Or is it not useful, since it needs a javascript highlighter and not a java highlighter?
