The Go Workshop

By: Delio D'Anna, Andrew Hayes, Sam Hennessy, Jeremy Leasor, Gobin Sougrakpam, Dániel Szabó

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.

This chapter introduced you to the time package of go, which allows you to reuse code that has been invented by other programmers and incorporated into the language. The goal was to teach you how to create, manipulate, and format time variables, and, in general, make you familiar with what you can do with the help of the time package. If you would like to further improve or dig deeper into what the package has to offer, you should check out the following link:

Timestamps and time manipulation are essential skills for every developer. Whether you have a big or small script put into production, the time module helps you to measure the elapsed time of actions and provide you with the logging of actions that happen during the execution. The most important thing about it, if used correctly, is that it helps you to easily trace back production problems to their roots.

The next chapter will introduce you to encoding and decoding JSON, that is, the...
