最近Stack Overflow上有一群讨厌perl的人,所以我想我应该把我的“关于你最喜欢的语言你讨厌的五件事”的问题带到Stack Overflow上。拿你最喜欢的语言来说,告诉我你讨厌它的五件事。这些可能只是让你烦恼的事情,承认的设计缺陷,公认的性能问题,或任何其他类别。你只需要讨厌它,它必须是你最喜欢的语言。

不要拿它和其他语言比较,也不要谈论你已经讨厌的语言。不要用你最喜欢的语言谈论你喜欢的事情。我只是想听到你讨厌但能容忍的东西,这样你就可以使用所有其他的东西,我想听到你希望别人使用的语言。

每当有人试图把他们最喜欢的语言强加给我时,我就会问这个问题,有时是面试问题。如果有人找不出他最喜欢的工具的5个缺点,那他对它还不够了解,不能提倡它,也不能利用它赚大钱。他还没有在足够多的不同情况下使用它来充分探索它。他把它作为一种文化或宗教来倡导,这意味着如果我不选择他最喜欢的技术,我就错了。

我不在乎你用什么语言。不想使用特定的语言?那就不要。你通过尽职调查做出了明智的选择,但仍然没有使用它?好吧。有时正确的答案是“你有一个强大的编程团队,有良好的实践和丰富的Bar经验。改成Foo是愚蠢的。”


This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.

憎恨并不是衡量人们了解多少的唯一尺度,但我发现它是一个相当不错的尺度。他们讨厌的事情也让我知道他们对这个话题的思考有多好。

JavaScript

Every script is executed in a single global 'namespace'...something which you have to look out for when working with scripts from different sources If a variable is used but hasnt been defined before hand, it is considered a global variable Browser vendors making up standards as they please, making coding for us developers using such a beautiful language harder than it should be Case-Sensitivity - considering that there is no decent IDE for developing js with compile-time checking Workarounds (such as the use of hasOwnProperty method) to perform some, otherwise simple operations.

C#

No easy way to check if a type is Numeric It means you are probably stuck using most of the microsoft stack, IIS and MSSQL Instead of being a specific tool for a specific problem, C# tries to be a language for every paradigm. Lack of community. Sure, there are starting to be open-source frameworks and libraries for C#. The same ones that have been available to Java developers for years. Hard to find good help. The internet is littered with poor examples of how to solve problems with C#. This goes back to problem #3.

C#

1)缺乏为值类型编写泛型的实际能力。例如,任何白痴(好吧,大多数白痴)都可以编写一个例程,用c++计算int, float, double等列表的标准偏差,它写起来很简单,易于阅读,并作为快速的非泛型代码执行。我认为,如果你能用c#写一些东西,接近于达到这三个中的任何一个,而在其他两个上又不荒谬,你就是一个真正伟大的程序员。

2)协方差和反方差,尽管这被添加到4。

3)非常糟糕的LINQ文档(好吧,并不是语言的一部分)。

4)尝试使用foreach/迭代器,当我每次都想做同样的事情,除了上次略有不同(如连接一串字符串与逗号之间的单词和最后两个)。如果我用一个IEnumerable来写它,它很难写和读,而用一个for (int I =0 I <…)它并没有好到哪里去,而且效率更低。

5)我知道我会收到抱怨,但是缺少受控的例外。这并不需要像在java中那样实现(框架开发人员确实提出了一些很好的观点,为什么他们没有这样做),但我很乐意看到编译器警告不喜欢受控异常的用户可以关闭。

Quenya

• Community is too small. It's next to impossible to get a good language-immersion program going when there's no easy to find another speaker nearby. • Irregular verbs. Yes, I know English and Spanish mentioned them, too, but Quenya was invented. Why does there still need to be irregular verbs? • No Unicode support. I have to have three different Tengwar fonts on my computer before I can read most messages, and several of them are poorly kerned. This wouldn't really be a huge issue given the existence of a Romanized transcription, but Tengwar is so beautiful, you don't not want to use it. • Not all concepts can be easily referenced in Quenya, leading to annoying circumlocutions, or resorting to Sindarin, Númenórean, or (Manwë save me) Klingon to get my point across.

生存巨:

标准库的奇怪之处:它并不总是显示最佳实践,而且文档不足 硬编码FunctionX, TupleX类 缺乏属性:getter和setter是分开的,这违反了DRY,并且使得像FRP这样的事情几乎不可能实现 需要= _来初始化属性

PHP

几乎每个标准函数都在全局作用域中 不一致的函数参数顺序 不一致的函数命名 不区分大小写的函数 脚本的行为可能会因php.ini文件的不同而有所不同 能够使用未定义的变量 在某些情况下,必须将结果赋值给变量,然后才能在函数中使用它

更主观地说:

动态类型
