Scala defined type

Let's make our own type!

You saw how to parameterize the entire code.

Try change MyType from Int to String.

This seem simple but it is a building block required to understand generic type later.

If you want to start now, try to replace MyType by the following code:

type SubType = Int type MyType = List[SubType]
Do you see how you can combine types together ? Like Lego !

List can be parameterized, we used it with Int and String in the past, but you can use any type you want.
