Our journey through the Scala design patterns has arrived at the group of behavioral design patterns.

In this chapter, we will focus on the following behavioral design patterns:
- Value object
- Null object
- Strategy
- Command
- Chain of responsibility
- Interpreter
This chapter and the next one will give some clarity about what behavioral design patterns are, where they are useful, and how to implement them in Scala. We will be following a path similar to the previous chapters where we presented the patterns, showed a class diagram and a code example, and finally, gave a few hints about ...
