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。

Python:

不得不假设我们有语言。我们做什么?

我使用Java,我最大的不满是字符串操作的低效率。当你使用+运算符时。说真的,难道编译器不能计算出我添加了多少字符串,然后在后台为我生成StringBuffer的东西吗?

通常,使用+的代码比StringBuffers操作序列更具可读性。

另外,我讨厌本机数组和集合框架之间的冗余。. toarray()的语法极其丑陋。

JavaScript

数字作为字符串-数学可以 数字令人沮丧 解释为字符串。5 + 2 = 52? 叽阿… 权限-所有最好的东西都需要用户的权限! 屏幕更新—浏览器必须处于稳定状态才能更新屏幕。似乎没有一种方法可以强制在脚本中间更新屏幕。 慢-虽然谷歌的Chrome很好… 浏览器的差异使语言的使用[审查]。

我讨厌Java(目前它是我最喜欢的语言)的五个方面,排名不分先后。

As much as I am a fan of Java Generics, there are a lot of oddities that arise from the way it was designed. As such there a myriad of annoying limitations with generics (some of which are the result of type-erasure). The way Object.clone() and the Cloneable interfaces work is totally broken. Instead of taking the high-road and making everything an object (a.la. SmallTalk), Sun wimped out created two distinct categories of data-types: Objects and primitives. As a result there are now two representations for fundamental data types and wierd curiosities such as boxing/unboxing and not being able to put primitives in a Collection. Swing is too complex. Don't get me wrong: there's a lot of cool stuff one can do with Swing but it is a great example of over-engineering. This final complaint is equally the fault of Sun and those whom have written XML libraries for Java. Java XML libraries are way too complicated. In order to simply read in an XML file, I often have to worry about what parser I am using: DOM or SAX? The APIs for each is equally confusing. Native support in the language for easily parsing/writing XML would be very nice. java.util.Date sucks. Not only is it unnecessarily complicated but all the useful methods have been deprecated (and replaced with others that increase complexity).
