e.peek â object
Instance Public methods
Returns the next object in the enumerator, but doesn't move the internal position forward. If the position is already at the end, StopIteration is raised.
Example
a = [1,2,3] e = a.to_enum p e.next #=> 1 p e.peek #=> 2 p e.peek #=> 2 p e.peek #=> 2 p e.next #=> 2 p e.next #=> 3 p e.peek #raises StopIteration
