 Replying to [comment:7 ocean90]:
 > In jQuery, `$( '<element />' )` is just a shorthand for `$(
 '<element></element>' )`. jQuery will not add `<element />` to the DOM,
 instead it uses `createElement( element )` under the hood.

 and

 I think that is true only if the element does not have any attributes.

 If the element has attributes (as in `<button type="button"
 class="browser" />`), then jQuery calls `buildFragment()`, which then
 creates a `div` element and uses `innerHTML`:
