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.

Learning ORM

The ORM module is used to communicate with relational databases (such as Postgres, MySQL, SQLite, MSSQL, and Oracle). The communication to the database happens from the programming languages (such as V, Python, or C#, to mention a few) using the objects that are created to reflect the database table schema.

At the time of writing this book, V's standard library (vlib) ships with a built-in ORM that supports Postgres, MySQL, and SQLite. It has planned support for the other two popular relational databases, namely MSSQL and Oracle.

Generally, each database defines a standard way to interact and query against the data and this is often referred to as Structured Query Language (SQL). Each of these databases has its version of SQL that we refer to as dialects. Each database has a different dialect that specifies how to communicate with the database to perform queries.

However, by using V's ORM, you don't need to learn about, write, or manage different...
