The instructions: Inside the setPlayerCards function, start by adding the map method to arr that will take in an empty callback function. Then, use the addition assignment += operator to assign the new array to playerCards.innerHTML.
You did it wrong. Reset the challenge step and use map on arr within the map create a callback function. Then use the addition assignment operator to set that arr.map(callbackfunc) to the playerCards.innerHTML

my understanding was a literal empty callback function.

this is a literal empty function. Leaving the parenthesis of map empty means you are not giving it an argument at all
