javascript - how to iterate a result of jquery selector

I want to iterate a result of query selector.

Html code

<nav id="navigation">
        <a href="#" tabindex="1" class="active_nav">nav1</a>
        <a href="#" tabindex="2">nav2</a>
        <a href="#"tabindex="3">nav3</a>
</nav>

when I use javascript

alert($("#navigation >a")[0]);

the result is the tag a href attribute I don't know why.

Use $.each

$("#navigation > a").each(function() {

     console.log(this.href)
});

$('#navigation > a')[0]
      ^              ^---- Selects the 1st dom object from the jQuery object
      |                    that is nothing but the index of the element among 
      |                    the list of elements
      |-------  Gives you children of nav(3 anchor tags in this case)  which is a
                jQuery object that contains the list of matched elements
