JavaScript中是否有类似C＃的lambda语法？ [英] Is there a C#-like lambda syntax in JavaScript?

问题描述

是否有支持lambda语法的JavaScript框架或后期处理器，如C＃？

Is there a framework or post processor for JavaScript that supports lambda syntax like in C#?

CoffeeScript中的函数定义看起来像lambdas但是我还没有考虑过他们彻底。

任何人都可以告诉我，我可以在JavaScript中使用lambda语法吗？

Can anyone tell me, can I use lambda syntax in JavaScript?

推荐答案

具有类似语法的Lambda函数包含在 ECMAscript 6 ，它们被称为箭头功能。例如：

Lambda functions with similar syntax are included in ECMAscript 6, they're known as "arrow functions". An example:

[duck，cat，goat]。filter（el => el.length> 3 ）; 返回 [duck，goat]

目前支持最近版本的 Firefox 和 Chrome 。

There's currently support in recent versions of Firefox and Chrome.

要在针对旧浏览器的JavaScript中使用此语法，可以使用可将ES 6编译为更广泛支持的版本的工具 - 例如工具 Babel 或 Traceur 。

To use this syntax in JavaScript that's targeting older browsers there are tools that can compile ES 6 to a more widely supported version - for example the tools Babel or Traceur.
