    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

    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。

    @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。
