Ask HN: Directory of JS Libs

I see at least one new JS lib being announced via the front page of HN everyday. Makes me wonder if there is a central place for discovering all the libraries, like an app store for JS libraries.

How do you keep track of the latest in the world of JS?

At the risk of stating the obvious, if you're doing server-side JavaScript/Node, there is https://npmjs.org/ or simply `npm search` from the command line.
