How to iterate through an array of objects in JavaScript using a for loop

My coding challenge progress

Disregard the comments, they are written in Danish because it's for a school task. I am in need of assistance. My loop is returning undefined values in my terminal, and I'm struggling to identify the problem. Despite functioning correctly and providing the right values, the presence of these 'undefined' values is bothering me.

UPDATE: The issue has been resolved by @aqq. Thank you for the assistance everyone!

Answer №1

It seems like the issue with the undefined call is related to the gørBeskedPersonlig function that is being invoked.

Upon examining your code, it appears that the function is not defined in the code snippet provided. You may need to comment out the following line to resolve the issue:

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

UPDATE: Upon further inspection of your code, it appears that the gørBeskedPersonlig function was not returning any value.

By updating the function to return a new value, the "undefined" error has been resolved.

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

Answer №2

Looks like there may be some console.log() statements within the function customizeMessage that are resulting in undefined output. Can you provide the code for that function?
