What is a node?

I'm coming across the term node more and more often these days and I'm still not exactly sure what it is. I know it has to do with JavaScript, but that's about it.

So, what is a node? How is it used in code?

Thanks!

Basically, a node is a generic name for any sort of object within the DOM.

You can change the properties of any node in your code.

This may help you understand: http://javascript.info/tutorial/dom-nodes

HOWEVER.. there's also Node.js, which might be what you've been hearing about? That's a different kettle of fish: http://nodejs.org/

It's the name of an element within the DOM. A paragraph object within an HTML doc would be considered one node of the HTML document object.
