Hello! Today, we'll delve into design patterns in Go with practical exercises that apply these fundamental principles to solve problems. Mastering these concepts will enhance your coding skills and understanding.

Our focus today is to strengthen your understanding of how and when to apply specific Go design concepts using structs, interfaces, and composition. These include Encapsulation, Abstraction, Polymorphism, and Composition through Go’s distinct approach.

We'll explore four real-life scenarios, examining which pattern is applicable and why, using Go’s unique features. Let's dive in!

In Go, Encapsulation is achieved using structs and package-level visibility. We use unexported fields and methods to control data access and promote data integrity.
