Working with optional values

Now, what happens when we want to make one of these values optional? For example, what if we want to give a default value to the URL? To do that, we can update our initialize method with the following syntax:

def initialize (title, description, url = "google.com") 

Now our program will have the same output even if we don't pass the url value while creating a new instance of the class. In this case, the output is unchanged when you have the following code:

api = ApiConnector.new("My title", "My cool description") 

This is how you can define optional arguments in an initialize method.
