Yeah. Seriously, why not dart. Any clue, anybody?

Dart requires loading a dart runtime js file on to the page, as far as I know. And I think they would claim Typescript is javascript + some extra stuff on top, whereas dart is a whole new language to learn.

Are there any organized efforts to fork the 1.x branch to sustain existing applications?

This isn't really a big jump, as they were using AtScript before which was really just a forked TypeScript: https://docs.google.com/document/d/11YUzC-1d0V1-Q3V0fQ7KSit9... They must have convinced Microsoft to accept their patches into mainline TypeScript.

The TypeScript program manager spoke about this just now at ng-conf (happening now) - their team reached out to the Angular team about this.

So Angular has gone from being written in plain JS, to Dart, to Atscript, and now Typescript? Why so much jumping around? Isn't that creating a lot of technical debt issues?

not really, everytime they switch they are filing for technical bankruptcy.

Do you really think writing a framework for a language in a different language is a good idea?

As if we didn't have enough reason to move on from Angular. Now you need to learn Typescript to contribute or grok the source files?

Angular 2 was being written in AtScript - in practice, not much has changed, just that Google and Microsoft are collaborating here and unifying efforts.

I guess as TypeScript is less likely to break existing JavaScript code base, as all JavaScript code are already valid TypeScript code.

I am pretty sure that TypeScript just adds type safety and is optional. I don't see this as a huge negative and I actually see this as a positive.

Just curious, what and why are all your reasons to move away from Angular?

AtScript was pretty much just TypeScript + annotations
