Why this code works? (if statement quesiton)
This might be a super easy answer and I just need for someone to explain it again.
So do code runs correctly if it’s written like that (just a part of the code):
if(nextSlide.length == 0) {
nextSlide = $('.slide').first();
nextDot = $('.dot').first();
}
currentDot.removeClass('active-dot');
nextDot.addClass('active-dot');
currentSlide.fadeOut(600).removeClass('active-slide');
nextSlide.fadeIn(600).addClass('active-slide');
However it won’t work correctly if the if statement is written after adding and removing classes from the slide and dots. Why?
Thanks.
