Summary:Pattern matching provides a powerful tool for declaring business logic in a concise and maintainable way. Scala blends traditional functional programming pattern matching with object-oriented concepts to provide a very powerful mechanism for writing programs. In this chapter, you’re going to explore the basics of pattern matching. Then you’re going to see how Scala’s case classes bridge object-oriented data encapsulation and function decomposition. Next, you’ll see how Scala’s pattern-matching constructs become functions that can be passed around and composed. Let's look at a simple example first.
