jquery child selector without parent

Question

I was looking at some code from a tutorial for creating a carousel menu and noticed parent child selectors without the parent. Never seen this before, and confused to what it is

Answer 1

This selector with a context:

$('> div', this)

gets flipped around to use a .find() like this:

$(this).find('> div')

which with the > child-selector is just:

$(this).children('div')

The others are doing the same deal, they could use .children(), and actually it'd be more efficient to do so.
