Empty Interface & Type Assertions

In Go, an empty interface (interface{}) is a special interface that can hold values of any type. Since Go is a statically typed language, normal variables must have a specific type, but the empty interface allows for dynamic typing when needed.

Additionally, type assertions enable extracting a specific type from an empty interface, making it possible to safely work with dynamic data.

Why Use Empty Interfaces and Type Assertions?

• Empty interfaces (interface{}) allow working with unknown or dynamic types.
