JS doesn't solve the client/server impedance mismatch at all. The JS community is struggling with designing libraries that work as well on the server as well as the client. As Ryan (Node.js) has said, I see JS going the way of PHP. That's great and that it will attract certain kinds of coders and certain kinds of projects. But setting programming back by a decade? Personally I find JS a much better foundation for learning FP principles than PHP - there's enough in there to guide people to the topics I've outlined above. In fact my interest in these topics arose from being a JS coder for 5 years! JS is the gateway drug to the new future.

"The JS community is struggling with designing libraries that work as well on the server as well as the client." Disagree. YUI3 was a library written for the web, but it was so well designed that it took one YUI engineer hacking around for a few days to get it fully running in Node.js. Now, some awesome stuff is happening and it's an area of focus for the YUI team. http://express.davglass.com/ http://express.davglass.com/ Mustache.js and Underscore.js are other examples of popular JS libraries that work great server-side right off the bat. The main one left out is jQuery, and that is a library written primarily for DOM manipulation, which isn't really the point server-side (most of the time). Once JSDOM is a bit more mature, I'm certain you'll see jQuery become more popular server-side.
