要回答模糊代码如何导致“25”的部分问题，请执行以下操作：

同：

!(+[]) + !(![])   + []

+[]

（数组上的一元

）将数组转换为整数，该整数表示

，

+0

为

同时，

！[]

将数组转换为布尔值（这是真的-Javascript中的任何对象都是真的），对该值的否定为

false

!(0)   + !(false) + []
true   + true     + []

true+true

将布尔值转换为整数并相加，得到

2                 + []

此加法将两个参数都转换为字符串，给出了

“2”+”

，即：

"2"

的完成方式类似：

!+[]+!![]+!![]+!![]+!![]
!(+[]) + !![] + !![] + !![] + !![]
true   + true + true + true + true
5

而

“2”+5

是

“25”

Python请求是文本浏览器，它们是否与JS交互？不，如果与JS交互，则不会与JS交互，我不会遇到此问题；\ux：有人能帮我回答我的问题吗？是JS。。。。它不能在文本浏览器中工作，女士们先生们，这与Cloudflare在启用“我受到攻击”模式时用于验证浏览器的代码完全相同。谢谢，您也理解其余的JavaScript代码吗？如果是的话，请你解释一下：）我知道其余部分是如何工作的，但是如果没有这个答案，我就做不到：DHi，你能解释一下你是如何通过这些测试的吗？：）

"2"

!+[]+!![]+!![]+!![]+!![]
!(+[]) + !![] + !![] + !![] + !![]
true   + true + true + true + true
5
