  这样理解就很容易了:  字符串用split进行分割以后所以就成为了一个数组，例如：

  var mychar="hello,javascript";

  进行分割以后就变成了这样一个样子：["h","e","l","l","0",",","j","a","v","a","s","c","r","i","p","t"]

  定义数组的时候: var myarry=["h","e","l","l","0",",","j","a","v","a","s","c","r","i","p","t"]

  所以在用document.write()进行输出的时候中间是用“，”作为分割的。

  是这样的，对于字符"-"用来代码制定划分数字，对于字符"."是用来划分字母的，最后显示出来是逗号。其实就是相应字符串分割成相应的字符。

  分割是将string转化成数组，所以打印出来时是逗号分割
