Inheritance vs Composition in Go: Which is Better?

Can you explain the difference between inheritance and composition in Go?

Sure! In Go, inheritance is not directly supported like in some other languages. Instead, Go uses composition, which allows you to build complex types by combining simpler ones.

Why is composition often preferred over inheritance?

Composition is preferred because it promotes code reuse and flexibility. It allows you to change the behavior of a type at runtime by composing it with different types.

Can you give me an example of composition in Go?

Absolutely! For instance, you can create a Car struct that includes an Engine struct. This way, you can easily swap out different engine types without modifying the Car struct itself.

What are some scenarios where inheritance might still be useful?

Inheritance can be useful in scenarios where you have a clear hierarchical relationship and want to share common behavior across multiple types, but it's less common in Go.
