Return Empty Slice in Golang

If you have to return an empty slice (of any type) there are three ways to do it.

  1. Return a direct slice:
func getNames() []string {
	return []string{}

2. Return a variable:

func getNames() []string {
	var names []string
	return names

3. Return the variable initialized in the function declaration and you don’t have to say what to return:

func getNames() (names []string) {

Note: The second and the third solution are the same.
