Flow | Maybe type defining

	/**
	* `Maybe` type allows us to type annotate a potentially `null` or `undefined` value.
	* They have the type `T\|void\|null` for some type `T`, meaning it is either type `T` or it is `undefined` or `null`.
	*/
	var message: ?string = null; //here I’m saying that message is either a `string`, or it’s `null` or `undefined`

	/**
	* You can also use maybe to indicate that an object property will be either of some type `T` or `undefined`.
	*
	* By putting the `?` next to the property name for `middleInitial`, you can indicate that this field is optional.
