In this chapter, we will discuss some of the important and useful FP (Functional Programming) principles of the Scala programming language. I assume that you are already familiar with Scala basics such as Scala REPL, Scala OOPs concepts, and more. If you are really new to the Scala world, it'll be helpful if you read some Scala basics first and come to us later.
In this chapter, you will learn the following topics:
- Scala App
- How to use Scala REPL
- Scala FP features
- Scala Functional Design Patterns
- Scala plug-in for IntelliJ IDEA
- The Scala Collections API
- Trait and its linearization rules
