For my Web App Development class, I was tasked with writing an "updateUserEmail" function, and I don't really know what I'm doing. So far I have this: async function updateUserEmail(req: Request, res: Response): Promise<void> { const { userId } = req.params as UserIdParam; // Get the user account const userFind = await getUserById(userId); if (!userFind) { res.sendStatus(404); // 404 Not Found return; } // Now update their profile views const user = await updateUserEmail(userId, newEmail); res.json(user); // Send back the user's data }.
