Summary
In this chapter, we covered various aspects of functional programming in C#. Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids mutable data and state changes. In C#, functional programming can be embraced using Lambda expressions, higher-order functions, immutability, and other functional concepts.
Key principles of functional programming include immutability (avoiding mutable data), pure functions (no side effects), higher-order functions (functions that take or return other functions), and first-class functions (functions treated as data).
Functional data transformation involves transforming data using pure functions to produce new data without modifying the original. Functional pipelines chain multiple data transformation operations together declaratively and concisely.
Functional programming provides techniques for handling errors more elegantly, such as Option types, the Maybe monad...
