SyntaxError: Unexpected identifier Node.js

Question

I'm making a simple web application and keep getting this error.

app.get("/campground/:id/comments/new",function(req,res){
    camp.findById(req.params.id)({
        if(err)
            console.log(err);
        else        
            res.render("comments/new",{campground:camp});
    });
});

and keep getting this error

 console.log(err);
 ^^^^^^^

If I remove error Handling,I get the error,

res.render("comments/new",{campground:camp});
   ^

SyntaxError: Unexpected token .

Can Anyone Help?

You're not using findById properly, it should have a callback function, something like this:

app.get("/campground/:id/comments/new",function(req, res, err){
    camp.findById(req.params.id, function(err, camp) {
        if(err) {
            console.log(err);
        } else {   
            res.render("comments/new",{campground:camp});
        }
    });
});
