Go Structs vs Interfaces: Use Cases

What are the main differences between structs and interfaces in Go?

Structs are used to define data structures, while interfaces define behavior. Structs hold data, interfaces define methods.

Can you give me an example of when to use a struct over an interface?

Use a struct when you need to represent a concrete data type, like a 'Car' with fields like 'Make' and 'Model'.

And when should I prefer an interface?

Prefer an interface when you want to define a contract for behavior, like 'Drivable', which can be implemented by different types.

What are some common use cases for interfaces in Go?

Common use cases include defining APIs, enabling polymorphism, and allowing for easier testing with mock implementations.
