Can you explain the concept of interfaces in Golang and how they are used?
In Golang, interfaces are a fundamental concept that allows for polymorphism and abstraction. An interface defines a set of methods that a type must implement to satisfy the interface. It provides a way to specify behavior without specifying the actual implementation. Here’s how interfaces work in Go: 1. Interface Declaration: An interface is declared using…
