the console is showing an empty string?

when I check the console in the browser like the teacher does in the video using createListItems(playlist) I get ' ' in return. From the looks of it, I wrote everything correctly. 

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

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

The first time through the for loop, i is 0. Since 0 > arr.length is false, the for loop is done.

Try changing for (let i = 0; i > arr.length; i++ ) { to for (let i = 0; i < arr.length; i++ ) {.

Thank you! I can't tell you how dumb I feel. I've been staring at this for about 30 min trying to figure it out and I missed that completely. Sometimes it is the tiniest thing. Thank you again!
