Overview of this book

Using Kotlin without taking advantage of its power and interoperability is like owning a sports car and never taking it out of the garage. While documentation and introductory resources can help you learn the basics of Kotlin, the fact that it’s a new language means that there are limited learning resources and code bases available in comparison to Java and other established languages. This Kotlin book will show you how to leverage software designs and concepts that have made Java the most dominant enterprise programming language. You’ll understand how Kotlin is a modern approach to object-oriented programming (OOP). This book will take you through the vast array of features that Kotlin provides over other languages. These features include seamless interoperability with Java, efficient syntax, built-in functional programming constructs, and support for creating your own DSL. Finally, you will gain an understanding of implementing practical design patterns and best practices to help you master the Kotlin language. By the end of the book, you'll have obtained an advanced understanding of Kotlin in order to be able to build production-grade applications.

Chapter 4: First-Class Functions

  1. What is the significance of the fun keyword?
  • The fun keyword is used to denote the start of a function definition.
  1. How do you add a parameter to a function?
  • You must add parentheses after the function name. Within the parentheses you must use the name:Type syntax.
  1. What are named arguments?
  • When passing arguments, you can specify which parameter to assign an argument value by including the parameter name followed by = and then the value.
  1. What are default parameter values?
  • You can specify a default value for a parameter that will be used if the parameter is omitted when passing arguments to a function call.
  1. How do you define a local function?
  • You define it like a regular function but within another function.
  1. What is a top-level function?
  • A function not associated with any class that is defined within any Kotlin file
