more accurate comparisons:
* coffeescript to ruby
* express to sinatra
* towerjs to rails

think of node.js as a thin wrapper gluing together google's v8 engine (this is the runtime interpreter of javascript and also the virtual machine), and libuv (this is the secret sauce to asynchronous input-output; it is a C project largely maintained by Joyent for Node.JS but was recently adopted by Ruby, as well). the whole point of it is to take javascript beyond the browser by giving it direct access to the operating system input output systems. making it able to be much more powerful.

things unique to node:
* continuation-passing style  callbacks; proving to be one of the most effective methods of managing asynchronous concurrency challenges.
* perhaps the most efficient event loop implementation; can do more with one core than most apps can do with several.
