What is the best way to test for an empty string in Go?

Question

Which method is best (more idomatic) for testing non-empty strings (in Go)?

if len(mystring) > 0 { }

Or:

if mystring != \"\"         


        

Answer 1

It would be cleaner and less error-prone to use a function like the one below:

func empty(s string) bool {
    return len(strings.TrimSpace(s)) == 0
}
