JavaScript:

All the coolest things are insanely complex, but then, all the coolness is also wrapped up in such a small amount of code that you feel stupid for struggling to follow it '+' is an absurd choice of operator for concatenation in a weakly-typed language. Were they trying to scare off the noobs? It's a cross-browser compatibility minefield (never mind if it's even turned on or not) It's generally untrusted - associated with scummery such as blocking the back button, pop-ups that never die, etc. It's nearly impossible to debug because there are only a few different error messages and a few different types (Number, String, Object, etc.)

如果不是jQuery，我可能还是会像以前一样讨厌它:)

c# / .net:

Classes should be sealed by default There should be no lock statement - instead, you should have specific locking objects, and there should be methods such as Acquire which return disposable lock tokens. Corollary: there shouldn't be a monitor for every object. GetHashCode() and Equals() shouldn't be in System.Object - not everything's suitable for hashing. Instead, have an IdentityComparer which does the same thing, and keep the IComparer<T>, IComparable<T>, IEqualityComparer<T> and IEquatable<T> interfaces for custom comparisons. Poor support for immutability Poor way of discovering extension methods - it should be a much more conscious decision than just the fact that I'm using a namespace.

这些都是我想出来的，明天问我，我会想出一个不同的5个:)

C:

Lack of distinction between function pointers (executable) and data pointers (you really don't want to execute this). Extreme unreadability. Making code look like it does what it does is orders of magnitude more difficult than making it do the task in the first place. Lack of clear support for lisp-think. Doing functional things is possible, barely, but it's not clear. Serious inconsistency between libraries about how error codes are returned. Antiquated string handling. The strings aren't strings, they're null-terminated blobs. This is all manner of wince-worthy.

Lisp:

()需要按shift键。每次我口齿不清的时候，我就把它和[]交换。

Python。

虽然前面提到了python处理作用域的奇怪方式，但我觉得最糟糕的结果是:

import random

def myFunction():

    if random.choice(True, False):
        myString = "blah blah blah"

    print myString

也就是说，if块内部的作用域与函数的其余部分相同，这意味着变量声明可以出现在条件分支内部，并且可以在条件分支外部访问。大多数语言要么阻止你这样做，要么至少为你提供某种严格的模式。

此函数有时会成功，但有时会抛出异常。虽然这是一个人为的例子，但这可能会导致一些微妙的问题。

经过一些思考后重写了这篇文章…

虽然我喜欢PHP，但我讨厌它的五个方面(排名不分先后):

内置函数中的命名和参数顺序不一致。 面向对象的数组方法多亏了SPL，但遗憾的是还没有字符串。 PHP本身没有真正的并发，只有通过托管web服务器的多处理 没有像JavaScript那样的异步调用 只能通过扩展进行操作码缓存。不是很糟糕，只是有点烦人。

这些是令我烦恼的语言特性(或缺乏)，但更大的问题是这些与人/社区相关的东西:

事实上，很多使用PHP的人，对编程和良好实践一无所知，从而产生了非常混乱的代码。JavaScript也有同样的问题。 大量的教程/书籍传授了非常糟糕的做法和风格。这可能是第三条的主要原因。 它的坏名声主要是因为第三条和第四条。

HyperTalk:

很久很久以前就死了 没有简单的赋值(你不能说a:= 3，你必须说把3放进a 没有嵌套函数 没有真正的数据结构，只有字符串。要创建“列表”，您可以使用itemDelimiter分隔项并手动转义它们。你也可以得到行和单词比如txt的第5行第2个单词

说句题外话，我认为HyperTalk最酷的独特功能之一是特殊的it变量:

ask "How many years old are you?"
answer "You are " & it*12 & " months old."
