Discussion on: Three useful Express middleware

Hi, I don't understand why you create the high order function like this

const removeEmptyProperties = () => {
return function(req, res, next) {
req.body = omitEmpty(req.body);
req.params = omitEmpty(req.params);
req.query = omitEmpty(req.query);
next();
};
};

and use it like this

app.use(removeEmptyProperties());

Isn't creating the function like this

const removeEmptyProperties = (req, res, next) => {
req.body = omitEmpty(req.body);
req.params = omitEmpty(req.params);
req.query = omitEmpty(req.query);
next();
};

and using it like this

app.use(removeEmptyProperties);

enough?
