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.

Introducing concurrency

Concurrency means running tasks concurrently. While this might seem like a very abstract definition, let's consider the following real-world example. You wake up in the morning of winter, and you need hot water to bathe. You can only bathe when the water is hot enough. However, you have other morning chores to finish off while the water gets hot. So, you turn on the water heater and then, let's say, you brush your teeth for some time while the water heater indicates the water is hot. Then, you switch off the water heater, enjoy a hot shower, and get ready for the day.

The advantage of concurrency is that you can do multiple things simultaneously that don't have to follow a specific order. So, in this scenario, you don't have to remain idle waiting for the water to get hot; you can finish brushing your teeth in parallel. So, the order the tasks are completed in is not very important.

The term parallel I used previously is being used...
