With a block given, calls the block with each successive element of self; stops if the block returns false or nil; returns a new array omitting those elements for which the block returned a truthy value; does not modify self:
Example
a = [0, 1, 2, 3, 4, 5] a.drop_while {|element| element < 3 } # => [3, 4, 5]
With no block given, returns a new Enumerator.
