Hacker news doesn't have that much to do with hacking these days either, do you think it should change?
I believe that jsdb.io is also a fine name for a database of js libraries. I find it easy to remember. While looking at the url might be misleading before you've visited, once you've seen the site it'll be clear.
BTW, I don't think jsdb is a bad name, but it's already taken.
It was also a steal for a four letter domain name :)
