What is polymorphism in Go and how does it work?

Polymorphism in Go allows different types to be treated as the same type through interfaces. It enables flexibility in code.

Can you give me an example of polymorphism in Go?

Sure! Here's a simple example: You can define an interface Shape with a method Area(). Different structs like Circle and Rectangle can implement this interface, allowing you to call Area() on any Shape type.

How do I define an interface in Go?

You define an interface using the type keyword. For example: type Shape interface { Area() float64 }.

What are the benefits of using polymorphism?

Polymorphism promotes code reusability and flexibility, allowing you to write more generic and maintainable code.
