This chapter provided a high-level overview of the Scala programming language. We looked at some of the object-oriented and functional programming aspects of Scala using applied examples. This chapter touched upon the array, list, and map functionalities of the Scala collection API. These data structures have numerous uses in the data analysis life cycle. The chapter also provided the necessary information to set up and install the Scala tools that are essential for understanding and applying the topics covered in subsequent chapters. Finally, a quick overview of the data-centric Scala libraries was provided. We will be making use of these libraries in the next few chapters to solve specific data life cycle problems.
In the next chapter, we will look at the data analysis life cycle and associated tasks.
