Parse and Analyze User Agent Strings User Agent Parser tool for network operations.

The tool works under the hood by utilizing the `UAParser` library from `ua-parser-js`, which employs a set of algorithms to break down the user agent string into its constituent parts. When a user inputs a user agent string, it is passed through the `parseUA` function, where it is trimmed and then parsed using the `UAParser` constructor. The resulting object contains properties such as browser, engine, os, device, and cpu, which are then extracted and stored in the component's state using React hooks like `useState` and `useMemo`. The tool also uses `useEffect` to auto-fill the current browser's user agent string on mount, and `useCallback` to handle copy operations. In terms of data structures, the parsed result is represented as a JavaScript object with nested properties, which can be easily converted to JSON format for further analysis or debugging.

The tool relies on modern JavaScript APIs like `navigator.userAgent` to detect the current browser's user agent string, and uses ES6+ features like destructuring and arrow functions to handle state updates and event handling. The input validation is handled using a combination of React's built-in validation features and custom logic to handle edge cases. On the frontend, the tool uses React hooks to manage state and side effects, and follows mobile-first responsive design principles to ensure a seamless user experience across different devices and screen sizes. The `copyToClipboard` function from the `@/lib/utils` module is used to handle copy operations, which works by using the browser's clipboard API to write the parsed result to the system clipboard. Overall, the tool's architecture is designed to be modular, efficient, and easy to maintain, with a focus on providing accurate and detailed information about user agent strings.
