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 $$ for state management.
\@Watch is used to listen for the changes of state variables.
$$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.
