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.

Iterative statements

During software development, you might need to process or handle each element of the collection such as an array or a map. Sometimes, you will want to access each element of the collection and change its value or just read it for further processing. In V, you can achieve this by writing iterative statements using for loops.

The for loop, which is used as an iterative statement in V, is used to iterate over the elements of a collection. The collection is generally an array that has elements of a certain data type, or it could be a map that holds data in the form of key-value pairs.

In this section, we will examine the very basic syntax of how to write a for loop in V. Then, we will explore various ways in which to work with for loops, including how to write the following:

  • A for loop on maps
  • A for loop on arrays
  • A for loop without an index on the array
  • A traditional C-style for loop
  • A reverse for loop
  • A for loop on a range
  • A...
