By: Navule Pavan Kumar Rao

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 1: Introduction to V Programming

The V programming language is a statically typed compiled programming language that's used to build maintainable and robust software applications. It comes with high performance and simplicity, which allows software programmers to do rapid prototyping of applications at scale. You can write simple and clean code with minimal abstraction using V. V comes with performance as fast as C. V is not derived from any other programming language and is written in V itself and compiles itself in under 1 second.

The design of V has been influenced by programming languages such as Go, Rust, Oberon, Swift, Kotlin, and Python. The V language has similar syntax compared to the popular Go programming language. It is a simple, fast, safe, and compiled programming language. V offers all safety features by default, such as immutable variables, immutable structs, and pure functions. V offers great support for concurrency that is on par with Go programming.

In this chapter, we will cover the following topics:

  • The past, present, and future of V
  • V is a statically typed and compiled programming language
  • Simple and maintainable syntax
  • Backward compatibility, stability, and easy to upgrade to future versions
  • Features of V programming
  • V as a framework
  • Operating systems V supports

By the end of this chapter, you will have learned about the V language and its features. You will also understand Vinix, an operating system (OS) written completely in V.

Let's begin our journey by understanding how V came into existence, who created it, and what its future is.
