1.使用sort()將數(shù)組進(jìn)行排序，代碼如下：

<script type="text/javascript">
?var myarr1 = new Array("Hello","John","love","JavaScript");
?var myarr2 = new Array("80","16","50","6","100","1");
?document.write(myarr1.sort()+"<br>");
?document.write(myarr2.sort());
</script>

運(yùn)行結(jié)果：

Hello,JavaScript,John,love
1,100,16,50,6,80

問題：上面的例子的結(jié)構(gòu)為什么是這樣的呢？
