Just a quick hint. Every DOM ID is available as a global variable out of the box.

Don't use that in actual code obviously. Just for show-casing/fiddling.

Yes, but only as long as no script overwrites the global reference.

<div id="oneId"></div>
// evil js
oneId = 'haha!';

console.log(oneId);

That comment is so ridiculous, you can even post it as a general reply to any JS code-including article.

What's the point?

The point here is that you probably shouldn't rely on global variables and better use the DOM methods. It is also much more probable that your IDs are overwritten by another script accidentially than DOM methods.

That's absolutely true! Never use that for actual productive code.
Just a quick tip for fiddling purposes.
