The maybe type represents the possibility of some value or nothing. It is often used instead of throwing an error or returning 'NULL'. The advantage of using a maybe type over 'NULL' is that it is both composable and requires the developer to explicitly acknowledge the potential absence of a value, helping to avoid the existence of unexpected behaviour.
