join()TypedArray对象的函数将类型化数组的内容作为单个字符串连接起来并返回它。对于此方法，您可以传递分隔符以分隔数组的元素。
其语法如下
typedArray.join(':')<html>
<head>
<title>JavaScript Array every Method</title>
</head>
<body>
<script type="text/javascript">
var int32View = new Int32Array([21, 19, 65, 21, 14, 66, 87, 55 ]);
document.write("<br>");
var contains = int32View.join('');
document.write("."+contains);
document.write("<br>");
document.write(int32View.join(':'));
document.write("<br>");
document.write(int32View.join('-'));
document.write("<br>");
document.write(int32View.join(' '));
</script>
</body>
</html>输出结果
