Hello! In our lesson today, we’re delving into polymorphism in Go. Polymorphism provides the ability for different types to be accessed through the same interface. This enables a single function to operate on multiple types. In Go, interfaces facilitate polymorphism by allowing various types to share behaviors without relying on a traditional class hierarchy. Let's explore how Go's type system provides this flexibility.

In Go, polymorphism is achieved through the use of interfaces. Interfaces specify a set of methods that different types can implement, thereby allowing these types to be manipulated consistently. Consider a graphical shape interface; whether the shape is a rectangle or a circle, the operations (such as calculating the area) may differ. Let’s illustrate how polymorphism functions in Go with an example using shapes.

In this example, the Shape interface defines an Area() method. Both the Rectangle and Circle structs implement this method, allowing them to be treated as a . Polymorphism enables the method to function differently depending on whether the shape is a rectangle or a circle.
