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

I like the forAll approach best so long as it fits your use case. It exits early which is great. However, if that doesn't fit here's another, only marginally more complex, approach.

With reduceOption you get no early exit, but you can clearly specify the value for the case where the list is empty.

val l = List(true, false, false, true)
val andAll = l.reduceOption(_ && _).getOrElse(false)
