这种语言的语法和结构使开发人员很容易开发简单且容易理解的函数。

The syntax and structure of the language make it easy to create small, easy-to-understand functions to build upon.

函数语言结构，如高阶和一级函数，能让我对抽象的理解更进一步，让我更多地将精力放在代码能做什么 而不是怎么做 上。

Functional language constructs such as higher-order and first-class functions allow me to climb one more rung up the abstraction ladder and focus more on what the code does rather than how it does it.

函数式语言依赖于一等函数(可在任何其他语言结构可能出现的地方出现的函数)作为参数和返回值。

Functional languages rely on first-class functions (functions that can appear anywhere any other language construct can appear) as parameters and return values. Figure 3 illustrates this concept.
