Ruby non_empty? method

Question

I want to use expression:

!([1,2,3] & [43,5]).empty?
=> false
!([1,2,3] & [3,5]).empty?
=> true

to check if two arrays contains at least one common value. And I wonder if there is a better way of doing it? Maybe something like:

 ([1,2,3] & [3,5]).non_empty?

How to write non_empty? method?

Answer 1

([1,2,3] & [3,5]).any?
