Infinite Loop

Continuous cycling

Infinite carousels cycle seamlessly from last to first.

Clone technique:

$1.$ Clone first slide after last

$2.$ Clone last slide before first

$3.$ Animate to clone

$4.$ Instantly jump to real slide (no transition)

Slide order: [Clone Last] [ $1$ ] [ $2$ ] [ $3$ ] [Clone First]

Transition logic:

// After animating to clone
setTimeout(() => {
  disableTransition();
  jumpToRealSlide();
  enableTransition();
}, transitionDuration);

Alternative: Use modulo math with instant repositioning.
