The Code I write wrong deliberately can run and work as well.

Challenge Manipulate Arrays With pop has an issue.

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

My code:

// 举例
var ourArray = [1,2,3];
var removedFromOurArray = ourArray.pop(); 
// 经过 pop 操作之后，removedFromOurArray 的值为 3, ourArray 的值为 [1,2]

// 初始化变量
var myArray = [["John", 23], ["cat", 2]];

// 请只修改这条注释以下的代码
var removedFromMyArray = myArray[myArray.length - 1];

When I run the code mentioned above, I surprisedly found that it can work as well ! That is WRONG, because myArray still has a second array. I deliberately remain the second children.

And when I switch to the FCC English Version, my code CANNOT PASS the test.
