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。

c++缺乏好的重构工具,缺乏受控异常

Java缺少模板,缺少const关键字

其他回答

C++

太容易随机破坏内存并创建几乎不可能找到的错误(尽管Valgrind在修复这个问题上走了很长的路)。 模板错误消息。 在使用模板时,很容易将所有内容都包含在一个文件中,然后进行愚蠢的编译。 标准库在现代是一个笑话(默认情况下仍然没有线程或网络?) 大量令人讨厌的C语言(特别是所有在short/int/unsigned/等之间的转换)。

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:)

我的常用语言是爪哇语。这就是我讨厌它的地方:

5)。缺少指针 4)。异常捕捉 3)。布尔类型 2)。BigDecimal类型 1)。c#爱好者和Java爱好者

布尔值可以为空。我觉得这是违反直觉的。

BigDecimal是一个库,而不是一个语言特性。我对BigDecimal和Exception捕获的烦恼主要源于编写测试类,这些测试类必须跳过一堆箍才能完成实际工作。我应该澄清一下,我对这些事情很恼火,我不打算游说改变。

Common Lisp

缺少提供更现代功能的标准库(套接字,线程,…) 是否可以使用映射到本机窗口系统的标准化UI Scheme将lambda表达式赋值给变量并将变量直接作为函数调用使用的能力看起来比APPLY for FUNCALL更整洁。我猜这是使用多个名称空间的副作用 标准化的库源代码级打包系统,以便可以从多个实现中轻松使用它们

我想知道强类型的口齿不清会是什么样子

C

bit fields -- they aren't well specified by the language and how they work is compiler dependent and architecture dependent. It's often hard to find where a particular symbol is defined in a large mass of code, esp. if that symbol is produced by a macro. Which reminds me... The preprocessor is a rather ugly hack, amenable to all sorts of abuse. lack of standard sized integers (remedied by uint*_t lately, but there is lots and lots of old code floating around out there with custom typedefs or #defines for DWORD, WORD, BYTE, etc.) Lack of something akin to Perl's cpan.org (would love to be wrong about that one.)

编辑: 在考虑C的CPAN时,我想……我该怎么称呼这样的东西,然后想到了“ccan”,然后谷歌了一下,我看到了这个: http://ccan.ozlabs.org/

不过,它似乎还处于起步阶段。
