Using a for loop in JavaScript to loop over an array of objects

My code and terminal

Just ignore the comments, they are in danish as it is for a school assignment.. I need some help. My loop keeps giving me an undefined value in my terminal, and I can't seem to find the issue. It is working as it should, and gives me the correct values, but still has those 'undefined' ones which irritates me.

EDIT: Has been fixed by @aqq, thx for the help everybody!

It seems that you have some console.log() in function gørBeskedPersonlig that is returning undefined. Send a code for that function.

As @dikuw mentioned the undefined call might be coming from the gørBeskedPersonlig function being called.

I don't see that function being defined in your code so that's probably it, try commenting out the following line:

console.log(gørBeskedPersonlig(katalog[index].navn));

UPDATE: After reviewing your code, i can see that the function gørBeskedPersonlig was not returning anything.

Updating it to return the new value has fixed the "undefined" error.

function gørBeskedPersonlig(navn){
    hemmeligBesked.splice(1,1,navn+'!');
    return hemmeligBesked.join(' ');
}
