题目：
    有一数组myArrray[1,2,3,4,5,6,7,8,9,’陆俊’,’是’,’最帅的人’]，现在希望在控制台将其倒序输出；image.png

    9.     <script>
    10.         function swap(sourceArry) {
    11.             let newArray = new Array();//存放最后的转置后的数据
    12.             let i = 0;
    13.             for (const key of sourceArry) {
    14.                 newArray[sourceArry.length - i - 1] = sourceArry[i++];
    15.             }
    16.             return newArray;
    17.         }
    18.         let myArray = [1,2,3,4,5,6,7,8,9,'陆俊','是','最帅的人'];
    19.         console.log(swap(myArray));
    20.     </script>
    21. </head>
    23. <body>
    25. </body>
    27. </html>

    上面是非就地逆置的，下面这一种是就地：

    <!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>数组内容就地逆置</title>
    <script>
        function swap(sourceArry) {
            for (let i = 0; i < sourceArry.length; i++) {
                sourceArry[i] = sourceArry[i] ^ sourceArry[sourceArry.length - i - 1];
            }
            return sourceArry;
        }
        let myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, '陆俊', '是', '最帅的人'];
        console.log(swap(myArray));
    </script>
</head>+

<body>

</body>

</html>


    其实这里也可以不写返回值，这里直接修改的就是原数组中的内容：

    <!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>数组内容就地逆置</title>
    <script>
        function swap(sourceArry) {
            for (let i = 0; i < sourceArry.length; i++) {
                sourceArry[i] = sourceArry[i] ^ sourceArry[sourceArry.length - i - 1];
            }
        }
        let myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, '陆俊', '是', '最帅的人'];
        console.log(myArray);
    </script>
</head>+
