Applying logical and to list of boolean values

Question

Consider the following list of Boolean values in Scala

List(true, false, false, true)

How would you using either foldRight or foldLeft emulate

Answer 1

Instead of using foldLeft/Right, you can also use forall(identity) for the logical AND, or exists(identity) for the logical OR.

edit: The benefit of these functions is the early exit. If forall hits a false or exists a true, they will immediately return.
