In a React component, if you need to dynamically use the value of one attribute (such as value) for another attribute (such as text), it is invalid to directly reference it through Featured.CircularProgressbar.value. The correct approach is to use React's useState Hook to manage these dynamic data and bind both value and text to the same state variable. This ensures controllability of component behavior and data synchronization, which is the key to building dynamic interactive UI.

For users who want to reduce website load times and automatically select specific categories, we reveal how SPA works - usually loading all data at once. Therefore, directly calling the API is an effective strategy to bypass heavy front-end rendering and quickly obtain the required information. It is especially suitable for scenarios where only data content is required rather than complete UI interaction.
