Overview of Other State Management Features

In addition to the component state and application state management mentioned in previous topics, ArkTS also provides @Watch, $$ and @Track for state management.

• @Watch listens for the changes of state variables.

• $$operator provides a TS variable by-reference to a built-in component so that the variable value and the internal state of that component are kept in sync.

• @Track applies to attribute-level updates of class objects. When a property decorated by @Track changes, only the UI associated with the property is updated.

• Freezing a Custom Component represents that the component is inactive and its state variable does not respond to updates.
