List is not stacked, just one long string.

My code seems correct but my list is not stacking in the output. It’s just one long string as in console output. Why?

const playlist = [
    "So What",
    "Respect",
    "What a Wonderful World",
    "At Last",
    "Three Little Birds",
    "The Way You Look Tonight"
];

const createListItems = (arr) => {
    let items = "";
    for(let i = 0; i < arr.length; i++) {
        items += `<li>${arr[i]}</li>`;
    }
    return items;
};

document.querySelector("main").innerHTML = `<ol>${playlist}</ol>`;

Your interpolation token is inserting the playlist directly (${playlist}).

But in the video, the token calls the function to process the playlist into list items (${createListItems(playlist)}).
