Welcome to the lesson on Polymorphism with Go. Polymorphism, an essential pillar of object-oriented programming (OOP), enables us to design versatile, legible, and modular code that promotes code reuse. In this lesson, you will understand Polymorphism and its implementation in Go.

The marvel of Polymorphism lies in its ability to treat different data types as identical forms, thus simplifying your code and boosting its extensibility.

Consider the management of a zoo that houses various animals, such as Tigers, Elephants, and Monkeys. Each animal type exhibits specific behaviors but shares common features like eating, thereby demonstrating Polymorphism.

Polymorphism in Go is implemented using Interfaces — a sophisticated collection of method signatures that allow different entities to follow standard interactions.

We demonstrate this with an example featuring the Shape interface and two structs — Circle and Rectangle.
