Option<A> provides a nullable value of type A. It's essentially the same
as A | undefined but with a lot of useful methods attached.
You can construct an Option using either the Some function to
wrap a present value of A, or the value None to signify a null
value. You can also convert a value that's A | undefined into an
Option by calling Option.from.
