anonymous variable的意思|示意

Lambda functions (or "anonymous functions," as they are often referred to) are simply throwaway functions that can be defined at any time and are typically bound to a variable.

lambda函数(或者通常所谓的“匿名函数”)是可以随时定义的简单抛弃型函数，并且通常都与变量绑定。

When a closure "captures" a variable it "lifts" the variable out of its local scope and effectively moves it into an anonymous object.

当一个闭包“捕获”一个变量时，它就会将这个变量提取出它的本地范围，移到一个匿名对象里。

Type Inference - the var keyword, which is necessary when using anonymous types, can also reduce redundancy in your other variable declarations.

类型推断—使用匿名类型时，关键字var必不可少。它还能减少你其他变量声明中的冗余。
