First GNOME JavaScript application

I started to learn the GNOME Developer Platform on Fedora 24 OS. Gnome is a desktop environment composed of free and open-source software that run on Linux. It is an international project that aims to develop software frameworks for the development of software, to program end-user applications based on these frameworks, and to coordinate efforts for internationalization and localization and accessibility of that software.

Is written in C, C++, JavaScript, Python and Vala. To contribute to a project in GNOME, it is first necessary to set up a development environment with the latest version. This will allow you to make changes, test them, and create patches. You need using Flatpak and an IDE called Builder. This is the recommended method for new contributors, and is the easiest way to get started. 

A tutorial for beginners and code samples is here.  And more is http://bitmodelling.blogspot.ro/ . Flatpak is the next-generation technology for building and installing desktop applications. It has the power to revolutionize the Linux desktop ecosystem.
