This extension helps you learn the Art language and Code RealTime by working on excercises. Such exercises can be found here.
Invoke the command Art Tutorial: Exercises and specify a folder that contains Art excercises. The exercises will be loaded into the workspace and a web view will open. Use that web view to:
Select which exercise to work on.
Open an Art file for that exercise. It typically provides an incomplete application, and the goal of the exercise is to complete it so it works according to the instructions.
If you get stuck you can view a hint with information on how to solve the exercise.
If you still are not able to solve the exercise, or are just short of time, you can view a solution.
At any time you can try your solution for the exercise by building and running the Art application.
When you feel ready with the exercise, you can mark it as completed and move on to another exercise.
