Overview of this book

Functional programming makes your application faster, improves performance, and increases your productivity. C# code is written at a higher level of abstraction, so that code will be closer to business requirements, abstracting away many low-level implementation details. This book bridges the language gap for C# developers by showing you how to create and consume functional constructs in C#. We also bridge the domain gap by showing how functional constructs can be applied in business scenarios. We’ll take you through lambda expressions and extension methods, and help you develop a deep understanding of the concepts and practices of LINQ and recursion in C#. By the end of the book, you will be able to write code using the best approach and will be able to perform unit testing in functional programming, changing how you write your applications and revolutionizing your projects.

Advantages of using extension methods in functional programming


Method chaining in functional programming relies on extension methods. As we have already discussed in Chapter 1, Tasting Functional Style in C#, method chaining will make our code easier to read since it can decrease the lines of code. For the sake of code readability in the extension method, let's take a look at the following code, which we can find in the CodeReadability.csproj project:

using System.Linq; 
namespace CodeReadability 
{ 
  public static class HelperMethods 
  { 
    public static string TrimAllSpace(string str) 
    { 
      string retValue = ""; 
      foreach (char c in str) 
      { 
        retValue +=!char.IsWhiteSpace(c) ?c.ToString() :""; 
      } 
      return retValue; 
    } 
    public static string Capitalize(string str) 
    { 
      string retValue = ""; 
      string[] allWords = str.Split(' '); 
      foreach...
