 ## @LocalStorageLink Decorator
 
-Two-way data binding can be established between a component and the **LocalStorage** through the component's state variable decorated by **@LocalStorageLink(*key*)**. Wherein, **key** is the attribute key value in the **LocalStorage**. When a component that contains a **@LocalStorageLink** decorated state variable is created, the state variable is initialized with the initial value of the **LocalStorage**. If no initial value is assigned for the **LocalStorage**, the state variable will use the value defined by **@LocalStorageLink**. Changes made to this variable in the component will be first synchronized to the **LocalStorage**, and then to other components of the bound ability.
