Question

我正在介绍 javaScript/jQuery 类，并且必须制作一个标题幻灯片，我无法让它工作，你能看看我可能犯了什么错误吗？我走到了死胡同，感觉就像我的头撞在墙上。它说我需要添加更多不是代码的输入，所以我在这里输入更多。请随时提出任何澄清问题，

"use strict";
$(document).ready( () => {
    let nextSlide = $("#slides img:first-child");
        
    setInterval( () => {   
        $("#caption").fadeOut(2000);
        $("#slide").fadeOut(2000,
            () => {
                if (nextSlide.next().length == 0) {
                    nextSlide = $("#slides img:first-child");
                }
                else {
                    nextSlide = nextSlide.next();
                }
                const nextSlideSource = nextSlide.attr("src");
                const nextCaption = nextSlide.attr("alt");
                $("#slide").attr("src", nextSlideSource).fadeIn(1000);                    
                $("#caption").text(nextCaption).fadeIn(1000);
            });    // end fadeOut()
    },
    1000);         // end setInterval()
});

#slides img {
    display: none;
}
#slide {
    width: 100%;
}

我在 jQuery 中的幻灯片代码有什么问题？
