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。

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:)

Haskell

Sometimes the type system feels backwards. What if I don't want the compiler to infer types for my variables? What if I want the opposite, where it does constraint checking on said variables? For example, instead of inferring the type of the elements of a list, it instead makes sure that they all belong to a particular typeclass. This is a subtle but huge difference that makes it difficult for me to program UIs. It can be done, but it takes more effort than it does in some other languages. Haskell rocks for the non-UI parts, but the UI I leave to an untyped language. Allowing the construction of infinite values leads to some really frustrating errors sometimes. NoMonomorphismRestriction. Bytestring handling bites me in the ass sometimes and you don't know it until your program crashes because you mixed them up improperly. Something is wrong here, when we are losing type information that should have prevented this. Typeclasses should be automatically derived for trivial cases, like witness types, but there's a strong potential for abuse there.

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。

Erlang

没有静态推断 就像在哈斯凯尔发现的一样。这 会导致运行时错误和一个 有认真写代码还是使用 透析器(1)发现 差异。动态类型是 慢的:也被认为是慢的; 与C、Java等语言相比，它几乎是未知的; 的lists(3)模块有时相当精简 我缺少用于列表处理的有用函数 (就像在数据。例如Haskell中的List); 让我在每句话的结尾都加上 在从句中，和。最后是后者。

但这只是因为VB6毒害了整整一代程序员

我在一个曾经是VB6商店的VB . net商店工作，而在这里工作的每一个曾经是VB6开发人员的人都顽固地拒绝学习任何关于. net的知识。他们编写的代码就像VB6一样，他们的应用程序就像VB6应用程序一样糟糕。我的老板非常不鼓励使用LINQ，因为她担心其他人很难理解，这是事实，因为没有人想要理解它。

我认为如果微软只使用c#，我们会过得更好，这让我很难受，因为我认为花括号远不如VB的冗长结束语句。
