In this chapter, we'll dive deeper into Kotlin's support for first-class functions and how that support enables us to rethink how we write our code. You'll learn, in detail, how Kotlin functions are flexible, concise, and powerful by examining different types of functions, such as single expression functions and local functions. Finally, we'll explore how to leverage Kotlin features such as default parameter values, extension functions, and higher-order functions to write expressive, concise, and flexible code that reduces boilerplate and is more convenient to use.
The following topics will be covered in this chapter:
- Understanding Kotlin's first-class support for functions
- Using named arguments and default parameter values to reduce boilerplate and increase the utility of our functions
- Examining different types of functions and how/when to use them
