A practical guide for developers transitioning from Object-Oriented Programming (Java, C#, C++) to Go.
If you come from an OOP background, Go may initially feel minimalistic or even too simple.
Concepts such as classes, inheritance hierarchies, annotations, and heavy frameworks are either absent or intentionally de-emphasized.
This is not a limitation.
Go is designed to optimize for clarity, explicit behavior, concurrency, and predictable performance, trading deep abstraction layers for simplicity and ease of reasoning.
This project explains the key paradigm shifts required to move from OOP-style thinking to Go’s compositional and pragmatic design.
It focuses on:
- how Go differs conceptually from classic OOP
- common pitfalls for developers coming from Java-style architectures
- practical guidelines for writing idiomatic, maintainable Go code
Go is not an OOP language.
It favors structs, small interfaces, explicit dependencies, and composition over inheritance and hidden behavior.
The documentation is written to be:
- easy to scan
- suitable for onboarding
- useful as a daily reference
