That's right, not content with just having Mario Bros. ported to Javascript we've now got Mario Kart (SNES version) to mess about with at work.

So far, it's just racing. No weapons or any of that fancy stuff. At the moment, you can choose from 3 different drivers (Mario, Luigi and Princess Peach) and 2 different maps (Mushroom Cup Round 1 and 2). There is no lap count, no timer and no finish. You can just race around forever and try to beat the others (it's not hard, especially if cut a few corners). The AI is rather crude, but seems to work ok for the time being.

You should hop on over and play Mario Kart JS for yourself.
