A panic unrolls the stack until it's recovered from. If it's not recovered the entire server will go down.

If the panic isn't recovered it will print a stack trace, if it is recovered you can get a stack trace with runtime.Caller().

Go's panics are exceptions.

Thanks!

If you don't use recover it takes the server down.
