Question
In the previous exercise, we set an authenticated property and a user object for every session created through the middleware.

Solution
It seems like you're asking for help with a Node.js application that uses sessions for authentication. Here's how you can complete the ensureAuthentication function:
function ensureAuthentication(req, res, next) {
if (req.session.authenticated) {
next();
} else {
res.redirect('/login');
}
}
This function checks if the authenticated property in the session exists and is set to true. If it is, the function calls next(), allowing the request to proceed to the next middleware or route handler. If the authenticated property is not set to true, the function redirects the user to the login page.
After you've added this function, you can start your Node.js app by typing node app.js into your terminal. This will start the server and you can then navigate to the app in your web browser to test the functionality.
Remember to press the "Check Work" button to verify your solution for each checkpoint.
