It can using pure or return or if working with just Maybe specifically then Maybe is defined like so: data Maybe a = Just a | Nothing So to make an X a Maybe X, you'd put a Just before a value of type X. For example:…
If you have a value "aValue :: a" and a monadic function of "mFunc :: (a -> Maybe b)" that's essentially just asking you to use `>>= :: Maybe a -> (a -> Maybe b) -> Maybe b` as well as `pure :: Applicative f => a -> f…
