Huh.  We take a more nuanced approach.  We block .js files directly attached
to an email message.  For looking inside zips, we block .js files UNLESS
there's also at least one .html, .htm or .css file also found in the zip.

A blanket block of .js would really annoy web developers who seem to mail
around zip files of projects (yeah, yeah, this "git" nonsense will never
catch on...)
