     You'll evolve this module as your application grows.

positive.code:   This code creates a browser platform for dynamic (JiT) compilation and
    bootstrap's the `AppModule` described above.
  
    该代码为动态 (JiT) 编译创建浏览器平台，并引导上面提到的`AppModule`。
  
    The _bootstrapping_ process sets up the execution environment,
    digs the _root_ `AppComponent` out of the module's `bootstrap` array, &nbsp;
    creates an instance of the component and inserts it within the element tag identified by the component's `selector`.
  
    引导过程搭建运行环境，从模块的`bootstrap`数组中提出*根*`AppComponent` —— 创建该组件的实例并将其插入到组件`selector`标识的元素标签中。
  
    The `AppComponent` selector &mdash; here and in most documentation samples &mdash; is `my-app` 
    so Angular looks for a `<my-app>` tag in the `index.html` like this one ...
  
    `AppComponent`选择器——在这里以及文档大部分例子中——都是`my-app`，所以 Angular 在`index.html`中查找像这样的`<my-app>`标签...

    Every Angular application must have a root `NgModule`, even the [QuickStart](../quickstart.html).
    You didn't see it but it was there.
  
    每个 Angular 应用必须有一个根`NgModule`，包括[《快速起步》](../quickstart.html)在内。
    你之前没有看到它，但它确定有。
  
    A script in the `index.html` generated a hidden `AppModule` and bootstrapped it for you
    so you could focus on the `AppComponent` and discover the _essential Angular_ more quickly.
  
    `index.html`中的一个脚本生成了隐藏的`AppModule`并引导它。这样你可以专注于`AppComponent`，以更快的了解_ Angular 的基础_。
  
    If you're feeling adventurous, add your own `AppModule` and `main.ts` to the
    live code in the _QuickStart_ plunker.
  
    如果你爱冒险，可以在《快速起步》plunker 的在线代码中添加自己的`AppModule`和`main.ts`。
  
    Remove the following `<script>` tag from the `index.html` and see _your_ work in action.
