I really don't understand the benefit of using fmt.Sprint compared to add strings together with +. Here is an example of both in use:

func main() {
    myString := fmt.Sprint("Hello", "world")
    fmt.Println(myString)
}

and

func main() {
    myString := "Hello " + "World"
    fmt.Println(myString)
}

What is the differences and benefits of each?

fmt.Sprint is good for concatenation different types of its parameters as it uses reflection under the hood. So, if you need to concat strings - use "+", it's much faster, but if you need to contact number and your profit fmt.Sprint just like that:

message := fmt.Sprint(500, "internal server error")
