I using angular 2 for my production project, but now I want to learn NativeScript for myself?
Can anybody helps me with learning roadmap?
Coming from an Angular-2 development I guess that you will want to learn NativeScrpt + Angular-2 and not NativeScript Core (there are some major differences). If that is the case I recommend going through this tutorial step by step. You will need installed Node.js(recommended 6.9.2 at this moment), NativeScript (latest), TypeScript.
