6 Example of an impure function
7 Refactor impure function to pure
8 Reduce code side effects
9 Don’t mutate input arguments
10 Use an immutable argument

Immutable Types
11 Principles of immutable types
12 Read-only properties

14 Use helper methods to create new instance
15 Use factory method to create instance

Side Effects and IO
16 Work with files
17 Calculate the total in pure function
18 Randomness in functional programming

Choose Expressions

20 Rewrite statements as expressions

Functional Functions
21 Use FuncT for first-class functions
22 Higher order functions

Function Composition and Pipelining
23 Composition patterns
24 Compose functions
25 Pipelining with extension methods
