Overview of this book

The Go Workshop will take the pain out of learning the Go programming language (also known as Golang). It is designed to teach you to be productive in building real-world software. Presented in an engaging, hands-on way, this book focuses on the features of Go that are used by professionals in their everyday work. Each concept is broken down, clearly explained, and followed up with activities to test your knowledge and build your practical skills. Your first steps will involve mastering Go syntax, working with variables and operators, and using core and complex types to hold data. Moving ahead, you will build your understanding of programming logic and implement Go algorithms to construct useful functions. As you progress, you'll discover how to handle errors, debug code to troubleshoot your applications, and implement polymorphism using interfaces. The later chapters will then teach you how to manage files, connect to a database, work with HTTP servers and REST APIs, and make use of concurrent programming. Throughout this Workshop, you'll work on a series of mini projects, including a shopping cart, a loan calculator, a working hours tracker, a web page counter, a code checker, and a user authentication system. By the end of this book, you'll have the knowledge and confidence to tackle your own ambitious projects with Go.

Introduction

In the previous chapter, we covered Go's core types. These types are critical to everything you'll do in Go, but it can be challenging to model more complex data. In modern computer software, we want to be able to group data and logic where possible. We also want to be able to make our logic reflect the real-world solutions we're building.

If you were building software for cars, you would ideally want a custom type that embodies a car. This type should be named "car" and it should have properties that can store things about what kind of car it is. The logic that affects the car, such as starting and stopping, should be associated with the car type. If we had to manage more than one car, we need to be able to group all the cars.

In this chapter, we'll learn about the features in Go that allow us to model the data part of this challenge. Then, in the next chapter, we'll solve the behavior part. By using custom types, you can extend...
