So, if we're going to append a LI to UL we should do this:

```
var list = document.createElement('li');
var ulist = document.createElement('ul');
ulist.appendChild(list);

```

what if I create a span, should I do this?

```
var list = document.createElement('li');
var ulist = document.createElement('ul);
var span = document.createElement('span');
span.appendChild(ulist);
ulist.appendChild(list);

```
