Challenge Escaping Literal Quotes in Strings has an issue.

Please describe how to reproduce this issue, and include links to screenshots if possible.

My code:

var myStr="I am a\"double quoted \" string inside \"double quotes\"";
// Change this line

var myStr="I am a "double quoted " string inside "double quotes"";

代码检验有点小问题，当中没有空格或多出几个空格，都通过不了的。

@mileyxiao 上面同学已经解决你的问题，空格导致。
正确的如下：

var myStr="I am a\"double quoted \" string inside \"double quotes\"";  // 你的代码
var myStr="I am a \"double quoted\" string inside \"double quotes\"";  // 我的代码
