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.

Channel properties

You can obtain information about a channel variable by accessing the properties it exposes. The properties of the channel include len, cap, and closed. These properties provide the following information about a channel at the time of accessing them:

  • cap is an integer property that indicates the capacity of the channel. This is 0 for the unbuffered channel. In the case of a buffered channel, the cap property indicates the maximum number of values a channel can hold.
  • len is an integer property that indicates the actual number of values that the channel holds at the time of accessing this property. At any given point in time, the len value can only be less than or equal to the cap property.
  • closed is a Boolean property, and when its value is true, it indicates that the channel is closed. If a channel is not closed, the value of the closed property will be false.
