In Go, the empty interface (interface{}) is a type that can hold a value of any type, since all types implement the empty interface. It is used for storing data of unknown type.

Type alias (type Alias = OriginalType) is simply another name for an existing type, not creating a new type, but allowing the use of a more convenient or understandable name.

Main differences:

  • The empty interface is a universal container for any values.
  • The type alias is a synonym for the existing type, not changing behavior.

Example:

var x interface{} = 42 // x can be of any type

type MyInt = int // MyInt is an alias for int
var y MyInt = 10
