this was my form: and I am using express app.js is the main file and index.js containes routes in which I have few routes

router.post('/submit', function(req, res, next) {
var item = {
    study: req.body.study,
    proffesion: req.body.proffesion,
    sleeping: req.body.sleeping,
    games: req.body.games
};
console.log(item);
res.render('/index');});
