We started this chapter by learning some of the main FP concepts, including concepts such as pure functions, higher-order functions, and immutability.
We also learned some of the main FP techniques, including techniques such as functional composition, function partial application, and currying.
Later, we learned what category theory is and how to work with some algebraic data types.
Finally, we learned about some FP libraries that can help us to put some of these techniques and concepts into practice in a real-world application.
In the next chapter, we will learn how to work with decorators.
