Conditional Statements in Go

1 min read

In Go, you use the if keyword to create a conditional statement. The condition itself is not wrapped in parentheses like it is in other programming languages. The block of code to be executed if a condition is met is wrapped in curly braces:

if name == "Zakk" {
  fmt.Println("Hello Zakk")
}

You can expand on this notation to include additional conditions using else and else if. If you are adding an explicit condition, you once again do not use parentheses:

func main() {
	age := 21
	if age >= 21 {
		fmt.Println("You may enter")
	} else if age == 20 {
		fmt.Println("Come back in a few months")
	} else {
		fmt.Println("You must be 21 or older to enter")
	}
}
