Summary
In this chapter, we dove into functional programming in C#, focusing on expressions and statements, and the powerful tools that C# provides to elevate your code. Let’s summarize the key takeaways:
- We learned the difference between expressions and statements. Functional programming often prefers expressions for their simple and direct style.
- We looked at expression-bodied members, which give a shorter and cleaner way to write methods and properties.
- We studied lambda expressions and anonymous methods. Both help in writing clear, brief, and contained code.
- We touched on expression trees, a special feature in C# that lets us handle code-like data. This is useful for things such as data queries in LINQ.
Throughout, our goal was to understand not just how to use these tools but also why and when they’re helpful.
Next, we’ll learn about pure functions, what makes a method “pure,” and what side effects mean.
