The .get() method grants access to the DOM nodes underlying each jQuery object. If the value of index is out of bounds â less than the negative number of elements or equal to or greater than the number of elements â it returns undefined. Consider a simple unordered list:
<ul> <li id="foo">foo</li> <li id="bar">bar</li> </ul>
With an index specified, .get( index ) retrieves a single element:
console.log( $( "li" ).get( 0 ) );
Since the index is zero-based, the first list item is returned:
<li id="foo">
Each jQuery object also masquerades as an array, so we can use the array dereferencing operator to get at the list item instead:
console.log( $( "li" )[ 0 ] );
However, this syntax lacks some of the additional capabilities of .get(), such as specifying a negative index:
console.log( $( "li" ).get( -1 ) );
A negative index is counted from the end of the matched set, so this example returns the last item in the list:
<li id="bar">
A zero-based integer indicating which element to retrieve.
Display the tag name of the click element.

Consider a simple unordered list:
<ul> <li id="foo">foo</li> <li id="bar">bar</li> </ul>
Without a parameter, .get() returns an array of all of the elements:
console.log( $( "li" ).get() );
All of the matched DOM nodes are returned by this call, contained in a standard array:
[<li id="foo">, <li id="bar">]
Select all divs in the document and return the DOM Elements as an Array; then use the built-in reverse() method to reverse that array.
