obj.class    → class

Returns the class of obj, now preferred over Object#type, as an object’s type in Ruby is only loosely tied to that object’s class. This method must always be called with an explicit receiver, as class is also a reserved word in Ruby.

1.class      #=> Fixnum
self.class   #=> Object
