Javascript/jQuery --> How to make loop so that after the last testimonial /li/ the whole ul will repeat again?

Question

How to make loop so that after the last testimonial /li/ the whole ul will repeat again (so after the last slide there will be first slide again)?

This is my jsFiddle: https://jsfiddle.net/t2zwo0fr/14/

This is the function which does interval, I want to enhance it with loop so that after the last testimonial /li/ there whole ul will repeat:

function blink() {
    if (active || slideIndex >= slideCount - 1) {
        return;
    }
    slideIndex++;
    active = true;
    $('ul').animate(
        {'left': $('ul').position().left-szer1slidu},
        3000,
        function() {
            { active = false; }
        }
    );  
}
setInterval(blink,1000);    

Answer 1

Well, when the animation reaches the third li , I would use appendChild to move the first li to the last position and every time the "previous" animation is called, I'd insertBefore the other way around.. but that's without jQuery. :p

Also, don't forget to update the position of the ul to still show the current li .
