#none? {|block| ... } ⇒ Array<String>

Enumerable#none? is the logical opposite of the builtin method Enumerable#any?. It returns true if and only if none of the elements in the collection satisfy the predicate.

If no predicate is provided, Enumerable#none? returns true if and only if none of the elements have a true value (i.e. not nil or false).

Examples:

[].none?                      # => true
[nil].none?                   # => true
[5,8,9].none?                 # => false
(1...10).none? { |n| n < 0 }  # => true
(1...10).none? { |n| n > 0 }  # => false
