Ask HN: What does "node" refer to in javascript code on this page?

I am trying to understand the javascript on this page to copy it for my app to use for voting. So any help is appreciated. Thanks.

Node refers to an HTML element.

HTML element: <p id="fun">test</p>

JS to get a pointer to that element: var node = document.getElementById("fun");

node.id = "really_fun";

How that affects the HTML element: <p id="really_fun">test</p>
