`@Component` tells Angular that this class *is an Angular component*.
The configuration object passed to the `@Component` method
specifies a CSS selector for an HTML element named `my-app`.
When Angular sees `my-app`, it will know to
create and display an instance of our component.
The configuration object passed to the `@Component` method has two
field, a `selector` and a `template`.
`@View` is another decoration that describes how our
component renders on the screen. This one is dead simple,
a single line of HTML announcing "My First Angular App".
The `selector` specifies a CSS selector for a custom HTML element named `my-app`.
Angular creates and displays an instance of our `AppComponent`
wherever it encounters a `my-app` element.
The `bootstrap` line tells Angular to start the application with this
The `template` field is the component's companion template
that tells Angular how to render a view.
Our template is a single line of HTML announcing "My First Angular App".
The `bootstrap` method tells Angular to start the application with this
component at the application root.
We'd be correct to guess that someday our application will
consist of more components arising in tree-like fashion from this root.

When the `noImplicitAny` flag is `true`, the compiler demands that we supply type information
unless the compiler can infer the type. It won't allow an identifier to default to the `any` type.
This setting is a preference, not a mandate.
Many of us prefer `noImplicitAny` because we want the TypeScript compiler to enforce type-safety vigorously.
That's one of the reasons we are writing our app in TypeScript.
Other people set this flag to `false` because they prefer more relaxed type checking.
Folks new to TypeScript are sometimes overwhelmed by the rigor;
they too may set the flag to `false` .. while they learn.
