javascript - mmenu IE11问题

Question

我只是使用mmenu脚本，并且在此行中收到IE11语法错误。

    "DOMContentLoaded", () => {

整个代码如下所示

document.addEventListener(
    "DOMContentLoaded", () => {
        new Mmenu( "#my-menu" );
    }
);

代码不在官方文档中-> https://mmenujs.com/docs/core/


我尝试了一些用function()等找到的不同解决方案。
但是他们都不为我工作。
也许其他人遇到了这个问题，可以帮助我。
更新:
现在我得到 对象不支持IE11上的属性或方法'append'

document.addEventListener("DOMContentLoaded", function() {
    
        new Mmenu( "#menu", {
           "extensions": [
              "pagedim-black",
              "position-right"
           ],
           navbar : {
                title : " "
            },
           "navbars": [
              {
                 "position": "top",
                 "content": [
                    "prev",
                    "title"
                 ]
              },
              {
                 "position": "bottom",
                 "content": [
                    "<div class='navshort'></div>",
                 ]
              }
           ]
        });     

} );

根据mmenu文档https://mmenujs.com/docs/

As of version 8, the mmenu.js plugin by default only supports ECMAScript 6 compliant browsers. For Internet Explorer 10 and 11, you'll need the JavaScript polyfills included in the package.

Version 7 should work in Internet Explorer 10 and 11 without any shortcomings, it should also work to some degree in Internet Explorer 9, but you'll need a matchMedia polyfill.

对于IE 10和11，您需要使用polyfills
