About GoXercise

About the Website

GoXercise was born from a simple desire: to document my journey learning Go in a way that might help others on the same path.

As I dove deeper into Go, I found myself taking notes, writing code examples, and creating little challenges to test my understanding. These notes eventually evolved into this interactive learning platform. What started as personal documentation became something I wanted to share with the world.

Why this approach? I believe the best way to truly understand a programming language is through hands-on practice. That’s why every chapter includes:

Runnable examples - See concepts in action, not just in theory
Interactive playground - Experiment and learn by doing
Practical exercises - Test your understanding immediately
Real-world patterns - Learn what actually matters in production code

GoXercise focuses on intermediate and advanced topics because there are already excellent resources for beginners (like the official Tour of Go). My goal is to bridge the gap between “I can write basic Go” and “I understand Go deeply enough to write production-quality code.”

This resource is and will always be completely free. I believe knowledge should be accessible to everyone, regardless of their financial situation.

About Me

I’m a developer based in The Netherlands with a passion for clean code, system design, and continuous learning.

About my relationship with Go: Go isn’t my day-to-day language at work - this is purely a passion project. That said, I fell in love with Go’s philosophy: simplicity, explicitness, and pragmatism. The language makes it easy to write code that’s both performant and maintainable. It’s a joy to work with.

I started learning Go because I was fascinated by its approach to concurrency and its growing ecosystem. What began as curiosity turned into a deep appreciation for the language’s design decisions. The more I learned, the more I wanted to share that knowledge.

Why document my learning journey publicly? Teaching is one of the best ways to solidify your own understanding. By creating this resource, I’m forced to truly understand concepts before explaining them. If I can explain it clearly enough for others to understand, I know I’ve mastered it myself.

When I’m not exploring Go, I enjoy building things, experimenting with new technologies, and learning from the developer community.
