JavaScript localStorage Explained: Save Data That Survives a Refresh | JavaScript Tutorial #12

✅ The catch: localStorage only stores text
✅ JSON.stringify to save arrays and objects, JSON.parse to load them
✅ Saving the to-do list on every change
✅ Loading saved tasks when the page opens
✅ Where localStorage lives, and what you should never store in it
🎯 Your challenge:
