Angular 2 is the next version of Google's massively popular MV* framework for building complex applications in the browser (and beyond).

Improvements made in Angular 2 js:

  1. Reducing Angular 2's payload size.
  2. Making the Angular CLI usable end to end throughout the development process.
  3. Creating a more developer-friendly route definition and link API for the Component Router.
  4. Support for animations.
  5. I18n and L10n support.

And there are even more cool things to come -- some we've already started on including:

  1. More documentation, particularly around ES5/ES6 usage.
  2. Even better startup and runtime performance
  3. An architectural style guide
  4. Unit and end-to-end testing improvements
  5. More support for mobile web and installable mobile apps
  6. Material Design components for Angular 2
  7. A tools platform for deep IDE support
  8. Better support for ES6 and Babel
