The method removes and returns the elements for which the block returns a true value. If no block is given, an Enumerator is returned instead. ``` numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] odd_numbers = numbers.extract! { |number| number.odd? } # => [1, 3, 5, 7, 9] numbers # => [0, 2, 4, 6, 8] ``` |
