Beyond Effective Go

Empower yourself with the ability to write high-performance code in Go, significantly enhancing the performance of your applications. Corey’s book provides practical and concise explanations and clear, easy-to-follow examples. Beyond Effective Go—Part 1: Achieving High-Performance is designed to equip you with the knowledge you need and enable you to apply it immediately, fostering a sense of capability and empowerment.

This series doesn’t waste time on the basics but delves straight into the solutions for the everyday challenges that professional programmers face. With clear explanations and real-world examples, you’ll gain the skills to build scalable and maintainable applications in Go that are directly relevant to your work.

Unlike many programming books, Beyond Effective Go focuses on the programmer and the code. Whether you’re building large-scale backend services or convenient automation tools, the book will help you write maintainable, high-quality code that meets the needs of your users, programmers, and business.

This book, Part 1 of the series, focuses on achieving high-performance code. You will learn which aspects of your application or code to focus on and when. You will have a suite of tools, software patterns, and recipes to make your life easier.

After reading this book, you will:

• Master the various concurrency interaction patterns and be able to apply the one that best fits the problem at hand.
• Know how to leverage Go’s profiler, execution tracing, and benchmarking tools to diagnose concurrency and performance issues.
• Understand when code needs optimizing, what needs optimizing, and how.
• Be able to quickly identify and avoid concurrency issues like deadlock, starvation, livelock, and data races.
• Be able to expertly apply Go’s concurrency primitives and avoid many of their gotchas.
• Have a catalog of concurrency and performance patterns that you can quickly apply to your projects.

Beyond Effective Go is an essential resource for programmers, software engineers, and software managers who want to make the most out of their Golang programming efforts.
