Network programming
A new "Server" tab in your microStudio project will allow you to implement a game server in microScript, then run it and test it - in real time, always. You won't have to install a real server, it will all happen with a simple click to start your server, then make your game clients join the server and start an online multiplayer game. When you will come to export your project, you will be able to export the server app as a standalone NodeJS application, ready to install on a "real" server.
