Responsive E-Commerce product page, SASS, JS and SwiperJS

Hello again!, this is my second proyect done in FrontendMentor, this time I went for a little more difficult challenge, I used SwiperJS instead of a natural slider because I found it better than the layout that was given for this solution!

Got me a bit of a headache the javascript this time and I think is a little bit spaguetti, but the scss went better this time, any feedback is welcome, thanks a lot!
