As I asked in this post I was wanting to know how compatible Typescript is with ES6, which Typescript 2.0 plans to support:
Should I use Traceur instead of Typescript to target ES5 but be ready for ES6
However as I read this post by google it appears that Traceur is used pretty heavily in the upcoming Angular 2.0.
So I'm trying to decide on whether to go with typescript or Traceur to be better ready for Angular 2.0 (my team will have less refactoring).
