Method: Enumerable#any?
- Defined in:
- enum.c
#any? {|obj| ... } ⇒ Boolean #any?(pattern) ⇒ Boolean
Passes each element of the collection to the given block. The method returns true
if the block ever returns a value other than false
or nil
. If the block is not given, Ruby adds an implicit block of { |obj| obj }
that will cause #any? to return true
if at least one of the collection members is not false
or nil
.
If instead a pattern is supplied, the method returns whether pattern === element
for any collection member.
%w[ant bear cat].any? { |word| word.length >= 3 } #=> true
%w[ant bear cat].any? { |word| word.length >= 4 } #=> true
%w[ant bear cat].any?(/d/) #=> false
[nil, true, 99].any?(Integer) #=> true
[nil, true, 99].any? #=> true
[].any? #=> false
