this works
app.get('/', (req, res) => {
res.render('index', {name: req.cookies.username});
});
this does not
app.get('/', (req, res) => {
const name = req.cookies.username;
res.render('index', name);
});

56,413 PointsIf you want to use the object literal shorthand you need to use the object brackets around name so it knows you are passing an object and not just the variable name.
res.render('index', {name}); // Same as res.render('index', { name: name });
