     We can think of an observable as an array whose items arrive asynchronously over time. 
     Observables help us manage asynchronous data, such as data coming from a backend service.
     Observables are used within Angular itself, including Angular's event system and its http client service.

     To use observables, Angular uses a third-party library called Reactive Extensions (RxJS).

+
     - The "source of truth" is the component. The validation is defined using code in the component.
+
+    - “真理来源”于组件。表单验证在组件代码中定义。

     - Each control is explicitly created in the component class with `new FormControl()` or with `FormBuilder`.

+
     - The template input elements do *not* use `ngModel`.
