How to getOrElse with another Option in Scala

Question

Let's assume that we have an option foo1 and an option foo2:

val foo1: Option[Foo]
val foo2: Option[Foo]

Is there an operator/function that allows me to return the value of the foo2 when foo1 is None?

val finalFoo: Option[Foo] = foo1.getOrElseOption(foo2)

The above getOrElseOption does not exist obviously. I know we can do sth like this, but it is somewhat verbose and hard to understand:

foo1.map(Some(_)).getOrElse(foo2).

[orElse](https://www.scala-lang.org/api/2.12.2/scala/Option.html#orElse[B%3E:A](alternative:=%3EOption[B]):Option[B]) — Andrey Tyukin, Nov 19 '18 at 22:12
What about [`orElse`](https://www.scala-lang.org/api/current/scala/Option.html#orElse[B%3E:A](alternative:=%3EOption[B]):Option[B]) ? — Luis Miguel Mejía Suárez, Nov 19 '18 at 22:12

Option works a bit like a partial function, so orElse will do what you want:

foo1 orElse foo2
