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 per official guidelines and from performance point of view they appear equivalent (ANisus answer), the s != "" would be better due to a syntactical advantage. s != "" will fail at compile time if the variable is not a string, while len(s) == 0 will pass for several other data types.
