Tell us what’s happening:

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. I am getting error in this , please help me clear this

Your code so far

<!-- file: index.html -->


/* file: styles.css */

Hello, an empty call back should be parenthese and an arrow => but no keyword.

3

Whenever you see a request for an empty callback function in fCC, they mean write an arrow function.

4

It does not require an arrow function. What your code is missing is

Then, use the addition assignment += operator to assign the new array to playerCards.innerHTML .

As an aside, that should never be true. If the requirement is for an arrow function, it should be stated in the requirements.

5

@lasjorg, does this mean you can write a call back with (function(){ })?

6

Yes, it should pass with a normal callback. It does for me.
