Recover from a Nothing with the `alt` method
Once we’re using Maybes throughout our code, it stands to reason that at some point we’ll get a Maybe and want to continue applying transformations. We might get a Nothing and want to perform those same transformations on some default value. In this lesson, we’ll do exactly that! We’ll see how we can use the
alt method on the Maybe to recover from a Nothing and continue applying transformations with a Just.
