They removed the option for ES2015 over Typescript in an earlier release. Not cool, since many people want to start (and have started) a project with ES2015 during the Beta and Angular 2 allows for both. That being said, Typescript builds on top of JS, so you can still use JS, just not explicitly mentioned anymore.
Yeah, I know that I can still use.
I’m just wondering how will be this upgrade. Till now all upgrades from the beta releases were easier (and smaller) than this to the rc0, and now the docs explicit mention the need to manage some .ts files
I’m wondering if it isn’t time to create a new project with TS and re-build the app.
