问题描述

就像我有 var arr = [1,2,3,4,5] ,我希望它成为 arr [ 1 , 2, 3, 4, 5] 。我尝试使用:

Like I have var arr = [1,2,3,4,5], I want this to become arr["1","2","3","4","5"]. I tried using:

var x = arr[0].toString(); //outputs "1"

但是当我执行 typeof x 输出数字。

but when I do typeof x it outputs "number".

如何转换为当我执行 typeof 时输出字符串?

How can I convert this that when I do typeof it will output "string"?
