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.

Learning different approaches to implement concurrent programs

Now that we have understood the benefits of concurrent programming over the sequential approach, it is beneficial for you to understand a couple of other ways to deal with spawning concurrent tasks in V. So far, the programming examples we've looked at have dealt with void functions. In the following sections, we will learn how to write concurrent code for anonymous functions and how to retrieve the results from the functions that have return values.

Spawning functions with return values to run concurrently

Till now, we have spawned tasks that do not return any value to the main thread to run concurrently. We accessed the handle to these concurrent tasks and waited for these tasks to finish. What if the concurrent task has a return value? In this section, we will alter the example of morning routines that we looked at in the preceding section, where we ran void functions concurrently.
