Position filter in jQuery

jQuery allows you to filter the elements selected based on their position in the collection. For example:

$('.article:eq(2)');

Selects the third element with the class article. Elements in a collection are numbered starting with 0.

$('.article:gt(1)');

From the collection of all elements with the class article, select all elements following the second one.

$('.article:lt(3)');

From the collection of all elements with the class article, select up to the first three.

$('.article:first');

Selects the first element with the class article

$('.article:last');

Selects the last element with the class article

$('.article:odd');

Selects the odd elements out of all the elements with the class article (zero-based index: 1,3,5,etc)

$('.article:even');

Selects the even elements out of all the elements with the class article (zero-based index: 0,2,4,etc)
