In the meantime, here's a of a useful feature you could add to one of Jonas’s projects: Feature: Save game state to localStorage (for the Pig Game or Budgety) Why: Allows users to reload the page without losing their data. How: Use localStorage.setItem() to save scores and settings, and localStorage.getItem() to load them on page load. Let me know, and I’ll help you implement it or suggest something better suited to your goal.

It sounds like you're referring to the popular by Jonas Schmedtmann on Udemy.
