C(好吧，这不是我最喜欢的，但当时还没人做过。)

套接字库语法。 没有函数重载。 c风格的字符串。 缓冲区溢出。 神秘的语法。我不知道有多少次我查到像atoi这样的东西，拍着我的额头，然后大喊“当然!”

编辑:如果我使用更多的库代码(就像我用套接字做的那样，但那些特别糟糕)，我可能会想出更多的库代码，但我已经觉得我选择C语言是在作弊。许多语言的存在只是为了取C语言的好的部分，取代坏的部分，这有点像在徒劳无益。

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#

我的大部分抱怨都与假设c++约定自动成为c#的最佳选择有关

Class接口中不允许静态。这仍然是课程的一部分。为什么它不能成为界面的一部分?我不得不想出这么愚蠢的变通办法。 区分大小写。我知道在这一点上它会破坏遗留的应用程序，但为什么不区分大小写不是一开始的规则

对于。net的好处之一(不是c#特有的)

编译器不够聪明。在。net 3中。X，编译器可以找出“var”在编译时，为什么不其他常见的优化?我们都知道string和StringBuilder / immutable和mutable的区别。为什么编译器不为你转换它在很多情况下，显然StringBuilder比多个connect .s更好?我相信在默认情况下，编译器可以为我们做大量的其他优化(带有否决选项)，并为我们节省大量的时间。

JavaScript

Function object syntax: f = new Function( "foo", "bar", "return foo+bar;" ); (It takes n arguments, the first n-1 are arguments for the function, then nth is the actual function, in string form. Which is just silly.) Function arguments can be repeated. f = new Function( "foo", "foo", "return foo;" ); The last repetition is the only one ever used, though: f( "bye", "hi" ) // returns "hi" f( "hi" ) // returns undefined E4X should just die. My users are always complaining that it doesn't work the way they think it will. Let's face it, when you need a page and a half of psuedocode for a setter, it's time to rethink things. A standard notion of stdin/stdout/stderr (and files!) would be nice. null != undefined It's irritating to have to handle them both. Sometimes it's useful, but most languages manage to limp along fine with one.

C#.

我最讨厌的是:

No multiple inheritance - imagine you could provide whatever GUI framework base class (Control, Window, whatever) with MVC - related stuff, etc... framework / base class agnostic! No "friend" keyword... I know, the RAD - victims would abuse it for all kinds of stinky code and for hilarious malpractices, but it would be nice for the OOD - guys to enforce the law of demeter No language integrated DBC features, there are the Contracts, but I would rather have that Spec# - style with a general purpose "!" - postfix operator No AOP (I don't get it... this language has attributes, it would have been SO EASY to add interception code in the compiler!) No weak event delegates - the observer pattern becomes nothing but a memory leak bait as it is now... :-(

Lua

我喜欢用Lua编程，但下面是让我头疼的事情:

没有办法用这种语言编写API——不像C .h文件或Java接口 语言有一流的功能，但有人忘记告诉设计库的人。 编写函数的语法太重量级了。 语法分为语句和表达式。 表达式形式是贫乏的:没有let形式，没有真正的条件表达式，……

尽管如此，我还是坚持认为Lua非常棒:-)
