is_subclass_of

  • We can check if an object in Ruby is a subclass of another object using the Object.kind_of? method.

    PHP

    class Dinosaur {}
class TRex extends Dinosaur {}
 
$t = new TRex;
$result = is_subclass_of($t, "Dinosaur");
var_export($result);
// => true

    Ruby

    class Dinosaur; end
class TRex < Dinosaur; end
 
t = TRex.new
p t.kind_of?(Dinosaur)
# => true
