Overview of this book

A new language on the block, V comes with a promising set of features such as fast compilation and interoperability with other programming languages. This is the first book on the V programming language, packed with concise information and a walkthrough of all the features you need to know to get started with the language. The book begins by covering the fundamentals to help you learn about the basic features of V and the suite of built-in libraries available within the V ecosystem. You'll become familiar with primitive data types, declaring variables, arrays, and maps. In addition to basic programming, you'll develop a solid understanding of the building blocks of programming, including functions, structs, and modules in the V programming language. As you advance through the chapters, you'll learn how to implement concurrency in V Programming, and finally learn how to write test cases for functions. This book takes you through an end-to-end project that will guide you to build fast and maintainable RESTful microservices by leveraging the power of V and its built-in libraries. By the end of this V programming book, you'll be well-versed with the V programming language and be able to start writing your own programs and applications.

Chapter 7: Functions

So far, throughout this book, we have learned about the basic programming features of V, including arrays, maps, conditionals, and iterative statements. It's time for us to learn about writing functions in V. Most programmers, when writing software applications, prefer to group a set of statements such as variable declarations and perform arithmetic or logical operations with them, or iterate over the elements of an array or map and then filter them according to their need. The art of wrapping or grouping a logically related set of statements, providing it with a name, and optionally providing input arguments and return types is often referred to as the process of writing a function.

Before we begin, here is a brief outline of the topics we will cover in this chapter:

  • Introducing functions
  • Understanding function types
  • Understanding function features

By the end of this chapter, you will have a solid understanding of the various types...
