模块化思维
正如前言中所讨论的，在我们开发软件项目时，复杂性似乎无处不在。抽
象也是如此，它将复杂性隐藏在我们不敢触及的“岩石”之下，这些岩石
是我们通往另一个世界的接口，让我们可以远离复杂性，几乎不会去想复
杂性。
JavaScript
语言也是如此。尽管动态编程语言很强大，但是当我们使
用它们时，往往更容易（甚至会不由自主地）写出复杂的程序。
我们首先讨论如何更好地将抽象、接口及其底层概念应用到我们的工作中。
如此一来，在处理项目、项目中的特性、特性中的功能模块，甚至一个函
数的分支时，我们就可以将需要关注的复杂性最小化。

模块化思维
（
module thinking
），就是要认识到复杂性（复杂的逻辑）
最终是不可避免的。同时，复杂性是可以被隐藏在接口之下的，用户几乎
不会看到或想到它。但一件很棘手的事情是，这个接口必须设计得很好，
我们才不会产生挫败感。这种挫败感可能会促使我们深入了解这个糟糕的

许程序代码会相对容易维护与阅读。
系统可以按粒度划分：我们将系统分为几个项目，一个项目由多个应用组成，
每个应用又包含几个层级，其中有数百个模块，由数千个函数组成。通过
对代码进行合理的模块化 ...
