block annotation-defn
:marked
When unqualified, _annotation_ refers to a Dart [metadata
annotation][metadata] (as opposed to, say, a type annotation). A metadata
annotation begins with the character `@`, followed by either a reference
to a compile-time constant (such as [`Component`](#component)) or a call
to a constant constructor. See the [Dart Language Guide][metadata] for
details.
The corresponding term in TypeScript and JavaScript is
[_decorator_](!{docsPath}/ts/latest/glossary.html#decorator).

block bootstrap-defn-top
:marked
We launch an Angular application by "bootstrapping" it with the
[bootstrap][bootstrap] method. The `bootstrap` method identifies an
application's top level "root" [Component](#component) and optionally
registers service [providers](#provider) with the [dependency injection
system](#dependency-injection).

block decorator-defn
:marked
When used in this guide, these JavaScript terms are taken as synonymous with
[annotation](#annotation).
block module-defn
//- Taken from the Dart Difference in guide/architecture.jade
:marked
In this guide, the term _module_ refers to a Dart compilation unit, such
as a library, or a package. (If a Dart file has no `library` or `part`
directive, then that file itself is a library and thus a compilation
unit.) For more information about compilation units, see
the chapter on "Libraries and Scripts" in the
[Dart Language Specification](https://www.dartlang.org/docs/spec/).
block routing-component-defn
:marked
A [Component](#component) with an attached router.
In most cases, the component became attached to a [router](#router) by means
of a `@RouterConfig` #{decorator} that defined routes to views controlled by this component.
The component's template has a `RouterOutlet` element where it can display views produced by the router.
It likely has anchor tags or buttons with `RouterLink` directives that users can click to navigate.
block append snake-case-defn
:marked
Library and file names are often spelled in snake_case. Examples include:
`angular2_tour_of_heroes` and `app_component.dart`.
block zone-defn
:marked
Zones are a mechanism for encapsulating and intercepting
a Dart application's asynchronous activity.
To learn more, consult the [zones article][zones].
