How to write this function in ES6 fat arrow?

Question

I want to rewrite this function in to ES6 fat arrow, but not sure how?

    passport.authenticate("local")(req, res, function(){
        res.redirect("/secret");
     });

I thought this might be the way but nope:

    passport.authenticate("local")((req, res)=>{
        res.redirect("/secret");
     });

Answer 1

  passport.authenticate("local")(req, res, () => {
        res.redirect("/secret");
     });

It can be done this way.

Answer 2

如果您不打算在箭头功能中进行任何其他操作，则可以这样做。

passport.authenticate("local")(req, res, () => res.redirect("/secret"));
