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.

Syntax to define a channel

In this section, we will look at the syntax for defining a channel. Channels are a built-in feature in V, and you are not required to import any package to use them. The chan keyword is used to define a channel in V. To define a channel, you can use the following syntax:

CHANNEL_VARIABLE := chan DATA_TYPE{OPTIONAL_CAPACITY: CAPACITY_VALUE}

In this syntax, the channel variable will be of the chan DATA_TYPE. OPTIONAL_CAPACITY type. This is a syntactical representation of the cap property that accepts an integer value. The cap property is available on a channel variable that represents the capacity of the values the channel could hold. The type could be any type, such as a primitive type, or it could be a struct, a map, or an array.

Having understood the basic syntax, we will learn about unbuffered channels and buffered channels in the following subsections.

Unbuffered channel

A channel defined without capacity is referred to as an unbuffered...
