Regarding the problem that the find method in Js does not support IE

Recently, I encountered a JavaScript problem during front-end development. 

    <script type="text/javascript">
        var arrayList = new Array();
        arrayList.push(1);
        arrayList.push(2);
        arrayList.push(3);
        arrayList.push(4);
        arrayList.find(function (val) {
            if (val == 4) {
                console.log(&#39;This is a test&#39;);
            }
        });
    </script>

Using Chrome and Firefox, the running results are normal. However, the error "The object does not support the find attribute or method" did appear in IE.

After reading the official document, I found that it does not support IE.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find
