AngularJS 2.0 - What's new? My Take

Before u Start:

Read the following to get insight on specifications over which the AngularJS 2.0 is built.

1.Angular JS is written in ES6. Simple explanation of ES6 features can be read from here.
2.Angular JS uses AtScript(@ script) - Angular's Extension of ES6 features to support annotations & decorators similar to annotations in Java.
3.Angular JS uses traceur transpiler. It allows the new and proposed future EcmaScript features to be used in browsers.
4.es6-shim.js - To add ES6 in current browsers. 

Annotations:

AtScript provides 3 types of annotations - Type Annotations, Field Annotations and MetaData Annotations.
Lets start for now with, 

             1.@Component - Indicates the class is a component
             2.@View- As the name suggests-it is the view of the component.It can be a HTML template.They add some meta data to the class in order to give it a specific meaning. They are a declarative way to add meta data to code.

How to create a Angular 2.0 Component?

Angular 2 works with a concept of components. Each component consist of 2 parts

1. The Annotation Section(@Component & @View) – This consist of the meta data (component selector, template) for that component
2. The Component Controller Section(Class) – This is a ES6 Class, from which the template would be reading the properties that are interpolated ({{…}}) inside it .

   import {  ComponentAnnotation as Component,
  ViewAnnotation as View,bootstrap} from 'angular2/angular2';

  @Component({
  selector: 'app'
  })
  @View({
    template: 'Hello {{ name }}'
   })
  class App{
    constructor() {
     this.name = 'Muthu!';
    }
  }
   bootstrap(App);
