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, you've learned how to create production-ready concurrent code, how to handle race conditions, and how to make sure that your code is concurrent-safe. You've learned how to use channels to make your goroutines communicate with each other and how to stop their executions using the context.

You've worked on several techniques to handle concurrent computation. In many real-life scenarios, you might just use functions and methods that handle concurrency for you, especially if you're doing web programming, but there are cases where you have to handle the work coming from some different sources by yourself. You need to match requests with your response through different channels. You might need to gather different data into one single routine from different ones. With what you've learned here, you'll be able to do all that. You'll be able to ensure you do not lose data by waiting for all the Goroutines to finish. You'll be...
