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

$('> div', this)

The this is important. It's a context parameter that makes the query equal to

$(this).children('div');

See the documentation for $() for more information; it specifically mentions this:

Internally, selector context is implemented with the .find() method, so $('span', this) is equivalent to $(this).find('span').

$(this).find('> div') means "the divs that are children of this, which is equal to $(this).children('div').
