I saw that the website http://panopticlick.eff.org/ gather info about your browser, which makes you unique, even without cookies or IP tracking.
My question: How do you use javascript to see this info?

There's a download in this article on corephp.com that includes javascript to fingerprint browsers and convert the results to an MD5 hash sum - probably not as heavyweight as panopticlick but it is pretty good.
