javascript - Angular 和 Controller 功能参数

Question

我最近一直在用 Angular 做一些工作，我注意到可以省略 Controller 函数中依赖项的名称数组。如果这样做， Controller 仍然可以正常工作，并且依赖项可以正常注入(inject)。

我确定我遗漏了什么。起这些名字的原因是什么？

请参阅 https://docs.angularjs.org/tutorial/step_05 中的“关于缩小的说明”段落

它用于在缩小后保留依赖项注入(inject)的字符串引用:

Since Angular infers the controller's dependencies from the names of arguments to the controller's constructor function, if you were to minify the JavaScript code for PhoneListCtrl controller, all of its function arguments would be minified as well, and the dependency injector would not be able to identify services correctly.
