Unpacking arguments in Go

You can define Go functions to accept a variable number of arguments using ... before the parameter type. Inside the function the arguments are treated as a slice. For example:

func printNums(nums ...int) {
	for i := range nums:
		fmt.Println(i)
}

To unpack a slice as arguments when calling a function, you can use ... after the slice. For example:

nums := []int{1,2,3,4,5,6,7,8}
printNums(nums...)
