The Array#any? extends the Enumerable#any? method. This method passes each element of the collection it is called upon (here, an Array) to a block or a pattern and return true if one of the block returns a truthy (Difference Between Boolean Values and Truthy/Falsey) or if the pattern is equal to at least one of the element.
If no block or pattern is provided, an implicit { |obj| obj| } block is passed in as an argument, which wil cause any? to return true if at least one of the collection elements is a truthy (not false or nil)
[10, 5, 3].any? { |element| element > 8 } # => true
%w[Ceci n'est pas une pipe].any?(/pipe/) # => true
