Tell us what’s happening:

The question says the map method would return a new array of player-card items separated by commas but I cant seem to see that, can anyone explain where that occurs

Your code so far

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


/* file: styles.css */


/* file: script.js */
// User Editable Region


  playerCards.innerHTML += arr.map(
    ({ name, position, number, isCaptain, nickname }) => {
     return `
        <div class="player-card">
          <h2>${isCaptain ? "(Captain)" : ""} ${name}</h2>
          <p>Position: ${position}</p>
          <p>Number: ${number}</p>
          <p>Nickname: ${nickname !== null ? nickname : "N/A"}</p>
        </div>
        //The question says the map method would return a new array of player-card items separated by commas but I cant seem to see that, can anyone explain where that occurs//

Without the join method, it will return a list of the player cards comma-separated. The join method ensures that no commas appear in the end product.

You can log the results to the console. First, log the mappedArray to see the comma-separated list, add the join() method to your map() method, and finally log the setPlayerCards function to see a list without comma separation.

Note that the mappedArray is just a variable storing this.
