What's the advantage in building this site with Node.js over JS/Jquery?

Since we're only querying for one username at a time, what would be the advantage of using Node.js?

(this question pertains to the "Build a Simple Dynamic Site with Node.js" lesson, in case this question didn't post where I intended it to)

You can make a real time chatroom. Plus it can have mulitple workers working vs php which is single thread.

Basically real time. Node is basically a written server by yourself.

streams video and audio live. Jquery is more front end making GUI buttons and animations. Javascript well it's all javascript.

It may not be. It might just be the tool they chose to teach because it is prevalently used and good to learn. Also, you can't use jQuery on the backend, and jQuery is just a JavaScript library. Node is a JS runtime that excels at I/O because it is non-block, as well as being fast and efficient. It is actually single threaded, and runs in its own process. You can do things like forking, clustering, and running child processes to increase performance. I'm not sure comparing it to PHP is quite fair.
