Explain the concept of interfaces in Go and how they promote code reusability.

In Go, interfaces play a crucial role in promoting code reusability and enabling polymorphism. They provide a way to define a set of method signatures that a type can implement. By adhering to the defined interface, a type automatically satisfies the contract specified by the interface. Let's delve into the concept of interfaces in Go and their role in code reusability: 1. Interface Definition: * An interface in Go is a collection of method signatures defined as a named type. * Syntax: `type InterfaceName interface { Method1() returnType1 Method2() returnType2 ... }` * Interfaces specify what methods a type must have to satisfy the interface, but they do not provide any implementation details. 2. Interface Implementation: * Any type that implements all the methods declared in an interface implicitly satisfies that interface. * There is no explicit declaration or inheritance required. It is purely based on method signature matching. * This allows different types to be ....
