I agree with you William; however, php and darkhttpd don't scale very well, because it lacks asynchronous I/O capability. Also, the current spec¹d Javascript is pretty close to the more perfect language compared to C, Java or Python. It also has the biggest user base of any language, by far and it is the only true language that works in all browsers and on the server. BTW, there are no bad parts, just bad programmers.
