Review Summary
Excellent work on this server implementation! I am approving your solution as it correctly meets all the functional requirements, from URL parsing and validation to proper JSON responses. One small suggestion for future improvement is to remove the redundant try...catch block in src/createServer.js. Since you already validate the toCase parameter on line 30, the catch block for an "unsupported case" error is unreachable. Removing it would make the code slightly cleaner. This is a minor point in an otherwise solid submission. Keep up the great work!

This try...catch block appears to handle an error scenario that should not be possible given the preceding validation. The toCase parameter is already checked against SUPPORTED_CASES on line 30. If that validation passes, convertToCase should not fail with an "unsupported case" error. If it could throw a different error, the hardcoded message here would be misleading to the client.
