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.

Implementing a real-life concurrency scenario programmatically

It is equally important for you to not just understand the concept of concurrency but also experience it by writing concurrent code using basic real-life examples. In this section, we will mimic the example of concurrency that we explained at the beginning of this chapter programmatically using three tasks. These are the early morning routine tasks we mentioned; that is, heating the water, brushing your teeth, and choosing a pair of clothes from your wardrobe.

Since I believe that adding the realistic times it takes to perform each of these tasks is trivial, I'll provide some dummy values in terms of seconds to mimic these tasks. Hence, I chose to represent the time taken for each of these tasks in a matter of seconds just for brevity. This makes it easier for us to run the code faster and understand the results in a neat and organized manner. The following table shows the times I am mimicking for each of the three...
