Why do I need the return statement in appendToLi function when I'm doing that?//See in the next step

function appendToLi(elementName,property,value){ const element = createElement(elementName,property,value); li.appendChild(element);

}

I think I need the return statement because when I am going to do that:appendToLi('label',"textContent","Confirmed").appendChild(createElement("input","type","checkbox")); :and when you use the appendChild, you need a reference from the node and without the return statement, I will get undefined ?

Am I right?

You are correct. To be able to chain functions, the front function must return an object that has the next one as one of its methods.
