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。

Ruby是我最喜欢的语言,以下是我不喜欢的语言:

绿色线程+阻塞C库=巨大的失败 慢得令人痛苦 标准库本身与其使用bang!方法 模块包含+扩展是混乱的。 “开放类”不能是范围-我想添加一个String#dostuff,但我不希望泄漏到所有的第三方库 没有二进制部署打包解决方案。

其他回答

我可以为Python添加另一个:

给定一个列表l = [l1, l2,…], ln],那么repr(l) = [repr(l1), repr(l2),…, repr(ln)],但str(l) != [str(l1), str(l2),…, str(ln)] (str(l) = repr(l))。之所以这样做,是因为列表中可能有模糊的条目,如l = ["foo], [bar,", "],["], str(l)将返回"[foo], [bar,],[]",这“可能会使用户感到困惑”。然而,这使得str不可能仅用于转储数据,因为list杀死了“仅以可读格式转储数据”。Augh !

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。

PHP:

人们永远无法确定某些几乎常见的扩展在所有web服务器上都可用。 试图成为未来的一切(goto,闭包,…) 对于没有经验的用户有很多安全风险 更多的操作符重载会很好 所有不学习如何使它正常工作的可怜的程序员,给它一个坏名声

尽管如此,PHP是(脚本)语言。: -)

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:)

VB。网

The behavior AndAlso / OrElse and And / Or seems backwards. Perhaps they should be switched. When can only be used for exception catching. The ability to do a When conditional would be nice for some other things. There is no friggin Refactoring in the VS IDE (not really the language's fault) like there is with C# Not <obj> Is Nothing. Yes, this has been remedied by IsNot, but for some reason I see the Not Is being used too often. (I see it much more frequently with devs who speak english as a second language, does it make better sense from that angle?) It doesn't require the () on ToString() and most functions. (Leads to sloppy coding habits) Having to do _ when breaking a line. It allows optional parameters. (Leads to sloppy coding habits) declaring an array is done by UpperBound and not by capacity. "Dim arr(2) as String" will actually hold 3 elements. Having = be a comparison and assignment operator.
