I'm not saying that there's anything wrong with JavaScript, but I'm just curious as to why you want it to be the only language on the server and the client. What do you see as its advantages over (Python|Ruby|PHP|Java|etc.)? Why would you want to tie yourself to a single language when you could have your choice of languages?
