_______ interface in Go can hold values of any type.

In Go, an empty interface (interface{}) is a special type that can hold values of any type. It is commonly used when you need to work with values of unknown types or when you want to design functions or data structures that are flexible enough to handle different types of input. However, using empty interfaces can lead to loss of type safety, so it's essential to use type assertions or type switches carefully when working with them.
