Question Echo web

When I initialized the struct and I called back role := model.Role{} but it didn’t return the data to me.

What does it mean? Is it a service for students like this one? Please, write more details. Thanks a lot.
And, BTW my carefree youth has passed and it’s time to start building a solid base position, based on my education and accumulated life experience. Roll up my sleeves and get to work. Please advise me where to start. Thank you all in advance.
If not difficult, write your answer as soon as possible.
