I have a site with some js on the homepage, the site seems to work until you sit on it for a few minutes than kind of breaks, freezes up, etc.

I have one index/homepage with a “script-new.js” being used and the slider and page sliding effects work. But this is the js that breaks the site I believe.
That site/page is here: https://www.alpha-wireless.com/index-test.htm

I also have another “test” index/homepage with “script.js”, with this script, it doesn’t seem to break after visiting the site/page for a few minutes, but the slider doesn’t work, nor do the page effects (which I’m not too worried about that at the minute).

The main code that I’m seeing being use for the “swiper-slide” appears to be the same for both scripts. And it looks like this:

if (plugins.swiper.length) {
            for (var i = 0; i < plugins.swiper.length; i++) {
                var s = $(plugins.swiper[i]),
                        pag = s.find(".swiper-pagination"),
                        next = s.find(".swiper-button-next"),
                        prev = s.find(".swiper-button-prev"),
                        bar = s.find(".swiper-scrollbar"),
                        swiperSlide = s.find(".swiper-slide");

                for (var j = 0; j < swiperSlide.length; j++) {
                    var $this = $(swiperSlide[j]),
                            url;

                    if (url = $this.attr("data-slide-bg")) {
                        $this.css({
                            "background-image": "url(" + url + ")",
                            "background-size": "cover"
                        })
                    }
                }

                swiperSlide.end()
                .find("[data-caption-animate]")
                .addClass("not-animated")
                .end();

                var swiperOptions = {
                    autoplay: {
                        delay: s.attr('data-autoplay') ? s.attr('data-autoplay') === "false" ? undefined : s.attr('data-autoplay') : 5000   
                    },

                    loop: isNoviBuilder ? false : s.attr('data-loop') !== "false",
                    simulateTouch: s.attr('data-simulate-touch') && !isNoviBuilder ? s.attr('data-simulate-touch') === "true" : false,

                        } : null : null,
                    },

                    },
                    on: {
                        init: function () {
                            toggleSwiperInnerVideos(this);
                            toggleSwiperCaptionAnimation(this);
                        },

                        transitionStart: function () {
                            toggleSwiperInnerVideos(this);
                        },
                        transitionEnd: function () {
                            var $buttonsWinona = $(this.slides[this.activeIndex]).find('.button-winona');
                            if ($buttonsWinona.length && !isNoviBuilder) {
                                initWinonaButtons($buttonsWinona);
                            }
                        }
                    }
                };

                if (s.attr('data-custom-slide-effect') === 'inter-leave-effect') {
                    var interleaveOffset = s.attr('data-inter-leave-offset') ? s.attr('data-inter-leave-offset') : -.7;
                    swiperOptions = $.extend(true, swiperOptions, makeInterLeaveEffectOptions(interleaveOffset));
                }

                s = new Swiper(plugins.swiper[i], swiperOptions);

                var container = $(pag);
                if (container.hasClass('swiper-pagination-marked')) {
                    container.append('<span class="swiper-pagination-mark"></span>');
                }
            }
        }

Any help or point in the right direction would be greatly appreciated.

Thank you in advance!
