JSAN (The Javascript Archive Network) was recently announced at the North American Perl Conference as a repository for Javascript code, simliar to the archive that Perl has (CPAN). When I first checked it out, it was pretty barebones, but now it has many more features and a growing number of packages for people to play with. I definitely recommend that you check out the service - especially some of the modules and their test frameworks - it all has a lot of potential. I plan on wrapping up some of my Javascript code in the upcoming weeks so that I can distribute it on this site. Based upon the clarity of the code that's already up there - I have a good mark to strive for.
