## From TS to ES6 to ES5
Since TypeScript is a superset of ES6 JavaScript, and ES6 itself is a superset of ES5, the
transformation of Typescript code all the way to ES5 javascript can be seen as "shedding"
features.
When going from TypeScript to ES6 with decorators, we mostly remove
[type annotations](https://www.typescriptlang.org/docs/handbook/basic-types.html)
, such as `string` or `boolean`, and
[class property modifiers](http://www.typescriptlang.org/docs/handbook/classes.html#public-private-and-protected-modifiers)
such as `public` and `private`.
The exception is type annotations used for dependency injection, which can be kept.
Going from ES6 with decorators to plain ES6 JavaScript we lose all
[decorators](https://www.typescriptlang.org/docs/handbook/decorators.html)
and the remaining type annotations.
We also lose class properties, which now have to be declared in the class constructor.
Finally, in the transition from ES6 to ES5 JavaScript the main missing features are `import`
statements and `class` declarations.
For ES6 transpilation we recommend using a similar setup as our TypeScript quickstart,
replacing TypeScript with [Babel](https://babeljs.io/) using the `es2015` preset.
To use decorators and annotations with Babel, install the
[`angular2`](https://github.com/shuhei/babel-plugin-angular2-annotations) preset as well.

We also wrap our code in an

These practices together prevent our code from
polluting the global scope.

### Constructors and Prototypes
### Metadata
ES5 JavaScript has no classes. We use the constructor
pattern instead which works with Angular as well as classes do.
Using Typescript or ES6 with decorators, we have access to *decorators*.
Most Angular classes have one or more *decorators* attached to provide configuration
and metadata.
For example, a component must have a
[`@Component`](../api/core/index/Component-decorator.html) decorator.

### Metadata with the Annotations Array
In JavaScript, we can attach an `annotations` array to a constructor
In ES5/6 JavaScript we can instead attach an `annotations` array to a class/constructor
to provide metadata.
Each item in the array corresponds to a TypeScript decorator.
Each item in the array corresponds to a decorator.
In the following example, we create a new instance of `Component` that corresponds
to the [`@Component`](../api/core/index/Component-decorator.html) TypeScript decorator.

### Metadata with The Class Convenience API
The pattern of creating a constructor and decorating it with metadata
is so common that Angular provides an alternative convenience API for it.
The pattern of creating a constructor and decorating it with metadata is so common that Angular
provides an alternative ES5 convenience class API for it for ES5 JavaScript.
This API lets us define everything in a single expression.
With this API we first call the `ng.core.Component` function,
followed by a chained `Class` method call. The argument to `Class`
is an object that defines the constructor and the instance methods
of the component:

### Interfaces
When defining classes that need to implement a certain method, it
is common to use TypeScript interfaces that enforce that the
method signature is correct. Component lifecycle methods like `ngOnInit`
are one example of this pattern. `ngOnInit` is defined in the `OnInit`
interface.

### Input and Output Decorators
In TypeScript, property decorators are often used to provide additional metadata
for components and directives.
In TypeScript and ES6 with decorators, property decorators are often used to provide additional
metadata for components and directives.
For [inputs and outputs](../guide/template-syntax.html#inputs-outputs), we use `@Input` and
`@Output` property decorators.
They may optionally specify input and output binding names if we want them to be different
from the class property names.

In this example, we add `inputs` and `outputs` array attributes

If we need a binding name that is different from the
property itself, we use the `propertyName: bindingName` syntax.

Since no type information is available in ES5/6 JavaScript, we must identify "injectables" in

We attach a `parameters` array to the constructor function.
Each array item is the dependency injection token that identifies the thing to be injected.
Often the token is the constructor function for the class-like dependency.

### Injection with the @Inject decorator
When the thing being injected doesn't correspond directly to a type,
we use the `@Inject()` decorator to supply the injection token.
When the thing being injected doesn't correspond directly to a type, we use the

In this example, we're injecting a string identified by the "heroName" token.

To achieve the same effect in ES5 JavaScript, use a nested array with the constructor
array notation in which the injection information precedes the constructor function itself.
To achieve the same effect in JavaScript, use the constructor array notation

by adding `new ng.core.Host()` or `ng.core.SkipSelf()` in the
