In this case the array of elements that have said class contains 6 elements (the buttons). If you were to select, from that array, the elements with even numberd indexes you'd select the first element (which has index 0), the third (with index 2) and the fifth one (with index 4).\r\n\r\nHope that helps clear things up"}}
