What is Native Script?

It is yet another attempt to offer a tool that allows you to develop cross-platform applications especially focused on mobile devices (iOS, Android and Windows).

It is JavaScript-based and gives access to the native APIs of each platform in a uniform way. This is an advantage over web development that has several restrictions on accessing device features, as well as getting a lot of web face, possibly even impairing usability.

It does not guarantee that 100% of the application will be multiplatform, but much will be written only once leaving a marginal portion that should be written more specifically to a platform. I think it's an interesting approach, I just do not know how much they could do in a satisfactory way.

It's important that native applications are generated, not a web application. JavaScript is just the writing language. it is not the entire infrastructure. This differs from the PhoneGap that is used to develop cross-platform, but is primarily web-based to achieve the goal.

It actually resembles the Xamarin that also provides native access to the APIs of each platform when C # or other languages .Net as a language. Apparently there is the advantage of not needing wrappers so any platform news is immediately available for NativeScript . Although I doubt it works so well, it seems a little marketing. They also promise to have a single base for the UI. To this day I have not seen a solution that works well. This is the first?

The learning curve seems to be small if you already dominates well JavaScript and understands the mobile development model. But you still need to learn the new APIs. If it's worth just the person can say. I do not even know if it's worth it: P
