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.

Introducing modules

Modules in V allow you to logically group related blocks or pieces of functionality. The concept of modules offers you the ability to structure the code base and makes the code look well organized and easily identifiable. Let's begin learning about the modular approach in V by looking at the syntax to define and import the module. We will also learn how to create a module with public functions and access them from outside the module.

The syntax to define a module

V allows you to define a module using the module keyword followed by the name of the module. The following code specifies the syntax of how to define a module:

module MY_MODULE

In the preceding syntax, MY_MODULE can be any name that signifies the functionality that is present inside the module. The module naming convention is similar to that of variables, as detailed in the Variable naming convention section of Chapter 3, Variables, Constants, and Code Comments.
