: Using expression-bodied members and switch expressions makes the code concise and focused on the result.
As the story continues, Alex learns to build complex logic by combining small, reusable functions—a process called . Using LINQ (Language Integrated Query) as a powerful declarative tool, Alex can process collections with simple, readable pipelines rather than messy nested loops. The Evolution: Better C# Code By the end of the journey, Alex's code has evolved: Functional Programming in C#: How to write bett...
: Since pure functions have no external dependencies, they are incredibly easy to unit test without complex mocks. Alex can process collections with simple
