For example, the application may contain problems such as:

• Incorrect useEffect dependencies

• Incorrect state updates

• Missing error handling

• Incorrect property names

• Rendering data before it is available

• Incorrect event-handler implementation

You’ll provide the code and the error message to an AI coding assistant with a prompt such as:
