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 11: Channels – An Advanced Concurrency Pattern

The term channel indicates a medium or a path that allows you to transfer information or data from one end to the other. In the context of concurrency, channels allow us to share data by establishing a communication channel between the concurrent tasks. These concurrent tasks are often termed coroutines, which share the data by communicating through the channels. Channels are advanced concurrency patterns in V that solve the problem of explicitly handling data synchronization techniques among coroutines.

We can communicate between the coroutines with the help of shared objects. In V, these can be structs, arrays, or maps. But the problem with this approach is that you need to take explicit care of concurrency synchronization techniques such as protecting the shared objects using locks such as the read-only rlock or the read/write lock to prevent data races, as we learned in the Sharing data between the main thread and...
