I am new to .js and want to change this arrow function to normal function, for personal interest

module.exports.endpoint = fn =>
(req, res) => {
    Promise.resolve(fn(req, res))
        .catch((err) => {
            this.jsonOutHandler(err, null, res);
        });
};

How to achieve it?

add `function` in front, surround the parameter(s) in brackets (here it's just `fn` ), remove the `=>`, add `{ }` around the body and a `return`. – VLAZ Apr 13 '20 at 10:15
`= function(fn) { return function(req, res) {` etc – Jaromanda X Apr 13 '20 at 10:15
module.exports.endpoint = function (fn) { return function fun(req, res) { return Promise.resolve(fn(req, res)) .catch(function (err) { return this.jsonOutHandler(err, null, res); }); }}; – M Fuat Apr 13 '20 at 10:17
@MFuatNUROĞLU doesn't return anything. – VLAZ Apr 13 '20 at 10:17
@VLAZ you are right, I've fixed it – M Fuat Apr 13 '20 at 10:19
