Today I added a major feature to CosmoPulse: a favorites system. I created it by using LocalStorage. This allows users to save their favorite astronomy pictures directly in their browser without needing a database.
While building these features, I learned more about:
- Working with multiple APIs

• Storing user data locally

• Creating reusable JavaScript functions

• Handling errors when API requests fail

A challenge I had was making sure the page updates correctly after saving favorites. After debugging, the system now works smoothly.
