  • The Goal of Angular v2.0 it should be declarative.
  • The  Syntax of Angular v2.0 are human-readable and human-writable.
  • The Angular v2.0 deals with server data in form of a JSON and its is structural types on the JSON as well as on the Angular API.
  • The Angular v2.0 will be written in ES6 and it compiled into ES5 using "traceur". The Angular users can write your code using ES6 or ES5 both are working fine in v2.0.
  • The Angular v2.0 have the ability to attach the "meta-data" to Angular framework  "Types" or your code.
