@netblaster08003,

+++++ flipboard the next && prev steps
You will have to keep a strict order in your code.....

s t e p s - - f o r - - n e x t S l i d e
-1
-1a create a selection of nextSlide (2 steps, capture 'active-slide, capture next() slide )'
-1b create a selection of nextDot
-2 check if selection of nextSlide is EMPTY
-2a if EMPTY change nextSlide selection to first slide
-2b and change nextDot selection to first Dot
-3 swap -active-slide- and -active-dot- class from current to next
Step3 is done by

   currentSlide.fadeOut(600).removeClass('active-slide');
   nextSlide.fadeIn(600).addClass('active-slide');
   currentDot.removeClass('active-dot');
   nextDot.addClass('active-dot');

s t e p s - - f o r - - p r e v S l i d e
-1
-1a create a selection of prevSlide
-1b create a selection of prevDot
-2 check if selection of prevSlide is EMPTY
-2a if EMPTY change prevSlide selection to last slide
-2b and change prevDot selection to last Dot
-3 swap -active-slide- and -active-dot- class from current to prev
Step3 is done by

    currentSlide.fadeOut(600).removeClass('active-slide');
    prevSlide.fadeIn(600).addClass('active-slide');
    currentDot.removeClass('active-dot');
    prevDot.addClass('active-dot');
