Method: Enumerable#max

Defined in:
enum.c

#max ⇒ Object #max {|a, b| ... } ⇒ Object

Returns the object in enum with the maximum value. The first form assumes all objects implement Comparable; the second uses the block to return a <=> b.

a = %w(albatross dog horse)
a.max                                   #=> "horse"
a.max { |a, b| a.length <=> b.length }  #=> "albatross"
