We also had a look at how the Scala compiler resolves implicits. Finally, we covered how implicits work, how to use them, and what kind of benefits they provide.

In this chapter, we'll cover the core concepts of functional programming like Pure functions, immutability, and higher-order functions. We'll build upon this understanding and introduce some of the design patterns that are prevalent in large functional programs that you'll no doubt run into once you start to use Scala libraries that focus on functional programming. Finally, we'll cover two popular functional programming ...
