adding the button to the constant 'lis'

On 4:43 the teacher said he'll store the button in the constant 'lis' and select them with the children property. Did he mean he'll store the list items? I don't get it, Can someone please explain?

Yes, lis is an array containing the list of items children to ul.

Once he has that, he proceeds to iterate within the array, and adds the buttons on all of them with the function attachListItemButtons(li) that he previously created.

const listUl = listDiv.querySelector('ul'); // <ul> with multiple <li> children elements.
const lis = listUl.children; //an array with all the lists found as children of <ul>

function attachListItemButtons(li){
     //Adds buttons with document.createElement('button');
}

//Finally, a for loop, where he iterates on lis.length, to give every list item multiple buttons.
