collection to ArrayInquirer
collection. The method returns true if any element from the 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.
variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet]) variants.any? # => true variants.any?(:phone, :tablet) # => true variants.any?('phone', 'desktop') # => true variants.any?(:desktop, :watch) # => false
