By: Navule Pavan Kumar Rao

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 5: Arrays and Maps

Now that we have understood basic concepts in V, including variables, constants, and primitive types, in this chapter, we will focus on arrays and maps. We will learn about the different ways in which to declare arrays and how to initialize them during their declaration using the various properties available to define an array. Additionally, we will explore how to use the in and << operators in arrays. Then, we will walk through the process of working with fixed-size arrays and multidimensional arrays. We will also gain a better understanding of arrays by implementing the most frequently performed operations on them, including cloning, sorting, and filtering techniques.

In this chapter, we will also learn about maps that hold data in the form of key-value pairs. Maps in V are often referred to as dictionaries just like other programming languages, such as C# and Python. We will examine how to work with maps and understand various ways in which we...
