In languages like Golang and Rust, you have the ability to call a panic. A panic is something that will immediately halt execution of a program with an error message and it will cause the program to exit early with an optional back trace. So we can actually say right here at the very top and we can say error. We are panicking or we're crashing the program. That's fine. So now you can see that immediately the text agent knows that this is not going to get executed. So if I run this yes unreachable statement right here, any code following this expression is unreachable. Yes, we're having a panic and you can see here threat main panic.error we're crashing the program. Perfect. So that's good. Well, that's not entirely good.
