If you come from an Object-Oriented Programming (OOP) background, Go might initially feel minimalistic or even “too simple”.
You may look for familiar constructs like classes, inheritance, annotations, generics, or frameworks, and not find them the same way.
But Go is designed with clarity, simplicity, and explicitness in mind — trading some abstraction for ease of reasoning, concurrency, and performance.
This guide highlights the main paradigm shifts you’ll encounter and provides pro-tips for writing idiomatic Go code.
Go isn’t OOP — it’s simple, pragmatic, and compositional.
Embrace structs, interfaces, and composition, and you’ll write cleaner, faster, and more maintainable systems.

This documentation breaks down concepts, idiomatic patterns, and migration tips in a way that's easy to grasp for developers coming from Java, C#, or other OOP backgrounds.

This guide was created collaboratively with the help of ChatGPT (GPT-5) to summarize and translate Go’s core philosophy for developers coming from Object-Oriented Programming backgrounds (like Java).
It blends official Go documentation, community wisdom, and AI-assisted synthesis to make learning idiomatic Go easier and more intuitive 🧠✨.
I believe that documentation should evolve with the community — so if you have suggestions, corrections, or improvements, feel free to open a pull request or share feedback! 💬🙌
Together, we can keep this guide clear, accurate, and helpful for everyone migrating to Go 🚀.
