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

As of now, the Go compiler generates identical code in both cases, so it is a matter of taste. GCCGo does generate different code, but barely anyone uses it so I wouldn't worry about that.
