Popular Libraries
By this point, you should have a good understanding of the main concepts behind functional programming such as pure functions, immutability, and higher-order functions. In addition to that, you should be familiar with some of the most popular abstractions used when writing functional programs. With all of this knowledge, you are well equipped to start looking into some of the popular functional programming libraries in Scala.
In this section, we'll look at some of the popular functional programming libraries from the Scala ecosystem. After this section, you should be able to:
