trying to break this code down to bite size chunks, bit its not working...

I was hoping this would create some elements on the page...

var body = document.getElementByTagName("body")
var ul = document.createElement("ul");
var li = document.createElement("li");
body.appendChild(ul);
ul.appendChild(li);

Am I way off or is it something simple that I missed?

When running your code, I got

"Uncaught TypeError: document.getElementByTagName is not a function".

Try removing the body variable and using 

document.body.appendChild(ul);

directly. This did the trick for me.

Yes, that certainly did the trick...how did you know to try that? It looked to me that mine followed the same kind of logic as yours, but yours worked and mine didn't. Is there some rule in this circumstance that I'm just not aware of yet?

I'm not certain of any rules (still very much learning the DOM), but I had just never seen body attached to a variable before and it didn't seem like there was anything else that it could be.
