Review Summary
Your solution is approved because the HTTP server correctly parses the incoming URL, splits the pathname into parts (ignoring doubled slashes by filtering out empty segments), and builds a query object from all query parameters as strings, returning them in a JSON response for GET requests as required. The behavior for paths like /hello/world/123 and paths with doubled slashes matches the specification, and the use of the URL and URLSearchParams APIs is appropriate and concise in src/createServer.js. One area you could improve is robustness for non-GET methods: in the request handler where you check req.method === 'GET', it would be better to explicitly send a 404 or 405 (and end the response) for other methods so clients don’t hang waiting for a response. Another minor improvement is to avoid depending solely on req.headers.host when constructing the URL, and instead provide a safe fallback like 'http://localhost' if the header is missing. You can also simplify the response by not setting res.statusMessage explicitly, since statusCode and Content-Type are usually sufficient, and consider adding basic error handling to guard against malformed requests. Overall, the core functional requirements are fully met, and these suggestions are refinements to make your server more robust and production-ready.
