let re = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/u;
//replace
prn("2015-01-02".replace(re, (matched, //  2015-01-02
    capture1, //  2015
    capture2, //  01
    capture3, //  02
    position, //  0
    S, //  2015-01-02
    groups //  {year, month, day}
    ) => { 
        let {year, month, day} = arguments[arguments.length - 1]; //
        //let {year, month, day}  = groups; //OK
        return `${day}/${month}/${year}`;
    }));

what result do you expect? What is the error message actually seen?

arguments [arguments.length-1] debugging observation, it is valuable and correct, but can not be assigned, too strange?
ask for advice, thank you!
(it"s OK to assign values directly with groups, needless to say. )


Arrow function without its own arguments, is just like not having its own this. You have a layer of functions nested here. Arguments is actually the arguments, of the outer function, so you don't find it. If you use str.replce (re,function () {}), there will be no problem
