Tell us what’s happening:

The instructions is to add the map method to the existing array, which will then take an empty callback function. Then, am supposed to use the addition assignment += operator to assign the new array to playerCards.innerHTML . I have tried several times, but it does not go through, and insists that the .map() method should take an empty callback function. What am I not getting right here, thanks.

Your code so far

 arr.map(function(){
    playerCards.innerHTML += playerCards});

this is not an empty callback function

the new array is the one returned by map, so you assign your

to something

Thanks for this, was able to figure it out. I was almost forgetting what an empty callback function is, referenced the MDN docs…
