Functional Scala

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
