    Hi S Sharif,

    Very nice article so far. As per my knowledge, if there will be firm solution for typescript compatibility then its gone really helps alot. Also switching to 2 will be more reliable.

    Angular1 and Angular2 are quite different. Angular2 is actually a complete rewrite not an improved Angular2. Between Angular1 and Angular2 there was also Angular.dart which already was a complete rewrite and in retrospect can be seen as a prototype for Angular2. Just to make it obvious how much difference is between Angular1 and Angular2.

    What is TypeScript?? Is it same like as ES6 specification?

    • S Sharif says:

      TypeScript is a free and open source programming language developed and maintained by Microsoft.It is a superset of JavaScript which primarily provides optional static typing and class-based object-oriented programming to the language. One of the big benefits is to enable IDEs to provide a richer environment for spotting common errors as you type the code.

    We are about to start a new project with Angular. With no release date announced, we are kind of confused about whether to wait 2.0 release date or go ahead with 1.4 ?

    Please suggest.

    • S Sharif says:

      Originally Google said they would support AngularJS 1.x for approx one year after the late-2015 release of 2.0. (so for the entire 2016), and they received a harsh reaction from the community.

      Then, they changed their tune, saying that they will support version 1 as long as there is a high demand. This demand will be measured somehow by how well the community adopts version 2 as opposed to 1. (let’s assume another year of updates, 2017)

      When it comes to job posts AngularJS is still HUGE from what I’ve seen, which shows that companies are still investing heavily in 1.x. for new projects.

      So, let’s say Google will abandon the project for 2018. AngularJS is still open source (not like Windows XP), so there’s an opportunity for others to pick up development from where Google left off. Even for version 1.4, Google states that:”This Angular version is the first to be run by a much broader community-oriented team, including many people from outside of the Google Angular team…”

      So will Angular 1.x. By the time 2.5 years have past, version 2.x will be more stable and the migration path will be proven and tested.
