Question

I have something like this…

$( 'ul li' ).each( function( index ) {

  $( this ).append( ',' );

} );

I need to know what index will be for last element, so I can do like this…

if ( index !== lastIndex ) {

  $( this ).append( ',' );

} else {

  $( this ).append( ';' );

}

Any ideas, guys?

var total = $('ul li').length;
$('ul li').each(function(index) {
    if (index === total - 1) {
        // this is the last one
    }
});
