Please talk to us about how the instructions are confusing. Thanks

The instructions asking you this:

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 didn’t have a callback function.

The map method is supposed to take an empty callback function as its argument.

The function (card) {
playerCards.innerHTML += card
}

is not an empty callback function, because it takes a parameter “card” and there are executable statements inside your function.

I also had problems with this step, but my question is a different one.

My previous code didn’t pass:

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

I eventually figured it out by passing in another form of empty callback functions.
(To not simply give out the answer, I won’t post it here)

What I do not understand is:
There seems to be two forms of empty callback functions.
Why is the empty callback function as provided above not acceptable in this step?
