Какова основная функция интерфейса Any в программировании?

In the Go language, the interface Any (before Go 1.18 — interface{}) represents a universal type that can hold a value of any type. Its main function is to enable working with data of unknown or arbitrary types, which is useful for creating generic functions and structures. For example, you can use Any to store elements of different types in a single slice or pass parameters to functions without strict typing:

var value Any = 42
value = "text"

func printValue(v Any) {
    fmt.Println(v)
}

printValue(123)
printValue("string")

Thus, Any serves to implement dynamic typing in a statically typed language.
