In Go, an interface that contains no methods is called an empty interface interface{}. It is a universal type that can hold a value of any type.

An interface without methods and an interface that allows any type are essentially the same, because the empty interface imposes no restrictions on the types it can contain.

Example:

var x interface{} // empty interface
x = 42           // can assign an int
x = "hello"    // can assign a string

Thus, the empty interface is a way in Go to express "any type". An interface without methods and an interface that allows any type are the same.
