直接上代码：

 <!DOCTYPE html>

 <html>

 <head>

 <meta charset="UTF-8">

 <title>uvi</title>

      <link rel="stylesheet" href="style.css" type="text/css">

 </head>

 <body>

    <script>

       var a=["hello","world"];

       var b=["uvi","ivu"];

       var c=a.concat(b);//数组合并

       document.write(c);

       var d=["","","","","",""];

       document.write(d.sort());//数组排序

       document.write(d.sort(function(a,b){

           return b-a;

       }));//数组降序

       var e=["a","b"];

       e.push("c")//数组的末尾追加字符

       document.write(e);

       var f = ["c","b","a"];

       document.write(f.reverse());//数组的反转

    </script>

    <div id = "timetxt"></div>

 </body>

 </html>
