What are super functions in Ruby?

What are super functions in Ruby?

Super functions in Ruby refer to the use of the super keyword, which allows a method to call its superclass's method.

Can you give me an example of how to use super in a class?

Sure! Here's a simple example:

class Parent
  def greet
    "Hello from Parent"
  end
end

class Child < Parent
  def greet
    super + " and Child"
  end
end

child = Child.new
puts child.greet  # Output: Hello from Parent and Child

What happens if I don't use super in the child class?

If you don't use super, the child class will not call the parent class's method, and you'll only get the child's method output.

Are there any limitations to using super?

Yes, super can only be used within instance methods and cannot be used in class methods or modules.
