Review Summary

Decision: APPROVE

Your server meets the core requirements: it creates an HTTP server, parses the URL into parts (ignoring empty segments from leading/trailing/multiple slashes), parses the query string into a key→string-value object, and returns a valid JSON response with the correct Content-Type. I did not find any functional blockers or missing features.

Minor, non-blocking suggestions for future robustness and readability:

• Consider using the WHATWG URL API (new URL(req.url, 'http://localhost')) to handle parsing reliably and percent-decoding of segments (e.g., mapping parts through decodeURIComponent).
• If you want to support repeated query keys (e.g., ?a=1&a=2), consider collecting multiple values into arrays instead of keeping only the last value.
• Small style cleanup: removing trailing commas after function calls can help with compatibility in very old Node.js versions.

Nice work—clean, concise, and correct implementation.
