# Any suggestions to a simpler way for the inner loop avoiding if, else if, else if?

In this video I stopped it before I got to the point of the solution suggestion because I thought that we were going to solve it using a innerloop looping through song, artist and lenght, to add all the commas, spacings and whatnot, and then an outer loop which would add the <li></li> to end of every element.

After coding it, the solution in the video were simpler but I'm still wondering if anyone can comment on my solution. I was really unsure about using the if, else if, else if to solve the phrasing of the sentences, and I wonder how someone experienced would've solved this.

"[Song], by [Artist] - [Length]"

```const playlist = [
['So What', 'Miles Davis', '9:04'],
['Respect', 'Aretha Franklin', '2:45'],
['What a Wonderful World', 'Louis Armstrong', '2:21'],
['At Last', 'Ella Fitzgerald', '4:18'],
['Three Little Birds', 'Bob Marley and the Wailers', '3:01'],
['The Way You Look Tonight', 'Frank Sinatra', '3:21']
];

function createListItems(arr) {
let items = '';
for (let i = 0; i < arr.length; i++) {
items += `<li>`;
for (let j = 0; j < arr[i].length; j++) {
if (j === 0) {
items += `\${arr[i][j]}, by `;
} else if (j === 1) {
items += `\${arr[i][j]} - `;
} else if (j === 2) {
items += `\${arr[i][j]}`;
}
}
items += `</li>`;
}
return items;
}

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