这些测试题2年前左右就见过了，当时错了很多，都是基础的不会，后来恶补了一下
已经很久没看了，现在重新测，发现还是有错的 0。0

再看了下题目，第4题是粗心错的，蛋疼。
第七题果然左摇右摆还是选错了。

唉，谁能讲解一下就好了，只知道自己错了，又不知道为什么是哪个答案。
@hussion ，
@xiaozi 你们好厉害！

Arrowing

@bzw875 F12自己运行一遍就知道答案了

xiaozi

@bzw875 我是后端工程师，其实这些都是基础的东西，你要是有耐心的话可以撸一遍javascript的文档。

表示第2题是看错了。

That's more than a half :(

第2题居然没发现语法错误，
第3题不熟悉delete的用法，
第6题考闭包，本来选对了，犹豫一下改错了，
第8题这种写法还不太熟，
第9题以为不会进入if判断，没想到可以，不懂，
第11题好懂，粗心了，
第12题，函数重复声明，后面覆盖前面？
第13题，不懂，
第14题，不懂。

第九题有问题。FF 是 1number，答案没得选。

@kmvan 第九题有问题。FF 是 1number，答案没得选。
因为你运行过一次，所以变量被改变了

@kmvan 你在前面定义了 `f` 吧

这些题最没意义的地方在于，解释器实现方式变一下，可能答案就变了。。。。真蛋疼

@qdwang 这几道题考的内容都是基于 ECMAScript 5 的，题目最开始也说过了…所以答案以后不会变的..
