course := Course{Title: "Go Mastery", Price: 149.99}
fmt.Println(course.Describe())Go has no classes -- a method is just a function with a "receiver"
(c Course) attached. There's no inheritance either; Go favors
composition, embedding one struct inside another to share behavior.
Try it yourself
Exercise: Add a Describe() method to Course with a receiver, then call it.
