So far we have seen expressions using the
Int type. We will need quite a few more types, and a lot more expressions, to create the kind of expressive programs we're aiming for.
In this chapter we will see how to write more complex expressions, and introduce some more of Scala's basic types. We'll then look at the
Image type, provided by the Doodle library, which allows us to create pictures. We'll focus our attention on computing with pictures, and later with animations, for a little while. Pictures offer us immediate creative opportunities, and they make our program output tangible in a way that other approaches can't deliver.
For this chapter you can continue to use the worksheet we've already created.
