Is there still a purpose to factory functions or should we always use classes?

I just finished the Javascript class lessons. https://www.codecademy.com/courses/introduction-to-javascript/lessons/classes/exercises/review-classes?action=resume_content_item

There are top questions at the bottom of the page. They are


  1. Assigning a value to a property without a setter

  2. Is there still a purpose to factory functions or should we always use classes?

Those links are dead but I would really love to read what they were talking about. Especially number 2 (which is also the title of this post)

Thank you for any contributions

As for the first question, the link provided in the exercise is working fine for me.

And here is an article I found with a better explanation for the second question.

Hope this helps.
