Overview
Array Inquirer
Wrapping an array in an ArrayInquirer
gives a friendlier way to check its string-like contents:
variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])
variants.phone? # => true
variants.tablet? # => true
variants.desktop? # => false

Instance Method Details
#any?(*candidates) ⇒ Boolean
Passes each element of candidates
collection to ArrayInquirer

collection is equal to the stringified or symbolized form of any element in the candidates
collection.
If candidates
collection is not given, method returns true.
