Why Angular v2.0? Why not Angular 1.x+?

Every AngularJs developer little bit confused and ask to angular and other community why angularjs 2.0? why not angular 1.x+? 

  1. First app with Angular 2 and ES6
  2. Integration of Angular 1 and Angular 2
  3. What are major changes in Angular 2?
  4. New Features of Angular 2
  5. What is ECMAScript ES6?
  6. What is Traceur compiler?
Today's I attend ngConf/ng-conf meeting I asked same question and the community speaker explained in detail and finally I got my answer. The Answers are as given below
  • In Angular v2.0, we are using classes more than in Angular v1.x+ and the ES6 has a better classes syntax than ES5.
  • 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.
  • I can say, AngularJs 2.0 is Predictable. 
  • I can say, AngularJs 2.0 is Tool able etc.
