Introduction
Local storage is like the memory of your app. Think about it:
- 📝 You have a to-do app.
- ❌ Every time you close the app, your tasks are gone.
- 🎩 Local storage is solution to this problem.
Why Do We Need Local Storage?
Wondering why local storage is a big deal? Here’s why:
- Persistence: Keep data even after the app is closed.
- Offline Access: Users can access their data without internet.
- Performance: Data on the device means faster access.
- User Experience: Apps that remember preferences = Happy users!
