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.

Adding code comments in V

Imagine a situation where you have started looking at a new repository that has a lot of code and you want to quickly understand what any particular function or piece of logic does. You can spend some time looking at the logic and you might come up with an assumption of what the piece of code actually does. Often, it is a tedious task for other programmers to spend time reading the code to understand what the code is doing. Most of the time, even the programmer who wrote the code tends to forget what the logic actually does and only recollects after spending time on what they wrote.

Most of the programming languages allow you to add comments to the code. These comments can be single-line comments or multiline comments.

Single-line comments

Single-line comments are used to write short details about the code being commented on that generally fit in a line. A single-line comment starts with a double forward slash, //, followed by the comment that you...
