Well ,because Typescript makes a huge codebase easier to read and maintain (though ES6 is a huge improvement, no question)

I used to use Coffee Script, which I still like, but ES6 clearly made Coffee Script less relevant. Typescript value is clearly in the type annotations and the support for ES6 ...

Another problem with Coffee Script is the fact that it evolves way to slowly and it is unlikely to support most of ES6 features because its core maintainers are clearly not interested in adding significant features. In fact that the main issue for me. Both Backbone and Underscore suffer from the same issues.

I see that a lot and find it highly subjective. I don't find es6 useful at all and will stick with coffeescript for the foreseeable future but that also has to do with my reasons for using it.
