在Javascript中，我认为以下是等价的:

a['title'] = "Syntactic sugar is good for yr teeth.";
a.title = "Syntactic sugar is good for yr teeth.";

大约20年前，我用一个编译器为一种叫做Coral的语言工作，它允许我声明只写变量!

不过，这是有道理的，因为它们是全球性的，被用作一种信号机制。一个进程写入值，另一个进程读取值。

Haskell's use of Maybe and Just. Maybe a is a type constructor that returns a type of Just a, but Maybe Int won't accept just an Int, it requires it to be a Just Int or Nothing. So in essence in haskell parlance Just Int is about as much of an Int as an apple is an orange. The only connection is that Just 5 returns a type of Maybe Interger, which can be constructed with the function Just and an Integer argument. This makes sense but is about as hard to explain as it can theoretically be, which is the purpose of haskell right? So is Just really JustKindaLikeButNotAtAll yea sorta, and is Maybe really a KindaLooksLikeOrIsNothing, yea sorta again.

-- Create a function that returns a Maybe Int, and return a 5, which know is definitly Int'able
>  let x :: Maybe Int; x = 5;
<interactive>:1:24:
    No instance for (Num (Maybe Int))
      arising from the literal `5' at <interactive>:1:24
    Possible fix: add an instance declaration for (Num (Maybe Int))
    In the expression: 5
    In the definition of `x': x = 5

>  Just 5  
Just 5
it :: Maybe Integer

    -- Create a function x which takes an Int
>  let x :: Int -> Int; x _ = 0;
x :: Int -> Int
-- Try to give it a Just Int
>  x $ Just 5                   

<interactive>:1:4:
    Couldn't match expected type `Int' against inferred type `Maybe t'
    In the second argument of `($)', namely `Just 5'
    In the expression: x $ Just 5
    In the definition of `it': it = x $ Just 5

祝你好运读到这篇文章，我希望它是正确的。

PHP

来自在线文档: string implode (string $glue, array $pieces) -用字符串连接数组元素 注意:由于历史原因，implode()可以以任意一种顺序接受其形参。

这是可行的:implode($someArray， $glue)

希望他们能在PHP 6中消除这些历史怪癖。

在ColdFusion中，文本值自动转换为各种数据类型，用于各种目的。我遇到了一个奇怪的问题，“00A”和“000”被返回为相等。事实证明，ColdFusion将“00A”解释为时间，转换为某种数字时间格式，并将其转换为0。“000”被转换为0。所以它们都被认为是相等的。那时我学习了字符串的比较函数。

在javaScript中，NaN是一个全局变量。
