why no quotations in datablock for appendChild() method?

Why is there no quotation in the appendChild() method below?

// function for creating item from bottom input tag
addItemButton.addEventListener('click', () => {

    let ul = document.getElementsByTagName('ul')[0];

    let li = document.createElement('li'); 

    li.textContent = addItemInput.value; 

    ul.appendChild(li); // why no quotations like this 'li'?


});

Shouldn't it look like this?

ul.appendChild('li');

Yes, if you were appending a li to a ul it would indeed be ul.appendChild('li');, but in this case there is a variable li that contains an Λ™liΛ™ element, and you are appending whatever is stored in the variable.
