I'm following quide in <http://api.jquery.com/jQuery.getJSON/> and everything is great except I'm puzzled about injection part.

It's hard for me to understand what this exactly does:

```
$('<ul/>', {
    'class': 'my-new-list',
    html: items.join('')
}).appendTo('body');

```

Well `appendTo()` is clear. But how it makes html out of JS array and how to remove wrapping? Can this be translated to group of simple commands?
