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.

Summary

In this chapter, we took a big step in working with Go's type system. We took the time to define what types are and why they are needed. We then explored each of the core types in Go. We started with the simple bool type, and we were able to show how critical it is to everything we do in our code. We then moved on to the number types. Go has lots of types for numbers, reflecting the control that Go likes to give developers when it comes to memory usage and accuracy. After numbers, we looked at how strings work and how they are closely related to the rune type. With the advent of multi-byte characters, it's easy to make a mess of your text data. Go has provided power built-in features to help you get it right. Lastly, we looked at nil and how you use it within Go.

The concepts you've learned in this chapter have armed you with the knowledge needed to tackle Go's more complex types, such as collections and structs. We'll be looking at these complex...
