Svelte Stores
What are Stores?
Stores are objects that contain values that can change over time. They're perfect for managing state that needs to be shared between components.
1. Writable Stores
Writable stores can be updated from anywhere. They have set and update methods.
Counter Example
Current count: 0
2. Readable Stores
Readable stores can only be set during creation. They're good for values that come from external sources.
Current Time
Time: 2:06:55 AM
This time automatically updates every second using a readable store.
3. Derived Stores
Derived stores depend on other stores and automatically update when their dependencies change.
Time Formatting
The time string above is a derived store based on the time store.
4. Custom Stores
You can create custom stores with additional methods for specific functionality.
