flow is a two-way binding with no data, the data is transmitted only from model to view, and each update is made easier by replacing the old UI component on the page with a completely new UI component.In fact, the biggest feature of react is that UI component and UI replace

method is called asynchronously, which guarantees that multiple setstate methods of synchronization will only trigger one render at a time, which can improve performance. Unlike props, state is the internal status of a component, which, in addition to being initialized, may be determined by props and then completely maintained by the component itself. Throughout the component's lifecycle, react strongly does not recommend modifying its own props, bec

"Android threading Mechanism"For performance reasons,Android UI operations are not thread-safe, which means that if there are multiple threads concurrently manipulating the UI component, it can cause thread safety issues. To solve this problem , Android has a simple rule : only allow the UI thread to modify the UI
