Multiple Return Functions

Go has built-in support for multiple return values. This feature is often used in idiomatic Go, for example to return both the result and error values from a function.

func vals() (int, int){
  return 1, 2
}

The (int, int) in the function signature above specifies that the function returns 2 ints.

Multiple assignments

// using the vals() function from above
a, b := vals()
