          **Handle undefined routes gracefully.**

Consider adding a default handler or more descriptive error logging for undefined routes.

-  const handler = RouteHandlers[pathname];
+  const handler = RouteHandlers[pathname] || RouteHandlers["/default"];

Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

  const handler = RouteHandlers[pathname] || RouteHandlers["/default"];
