difference btw creating node with Appendchild vs brute text ex : '<li></li>'

So the teacher solution create all the li with back quotes but I appendchild and create element. here is my code : function builder (data) { const div = document.getElementById("employeeList"); const ul = document.createElement("UL");

ul.classList.add("bulleted");
div.appendChild(ul);
for (let i = 0; i < data.length; i++)
{
    let li = document.createElement("LI");

    if (data[i].inoffice == true)
        li.classList.add("in");
    else
        li.classList.add("out");
    li.textContent = data[i].name;
    ul.appendChild(li);
}

}; Which method is better and why? Thanks in advance

You forgot to provide a reference to the course example, but just in general there are often multiple ways to accomplish a specific thing.

In more complex code you may find that one method might save some steps or otherwise make the code more efficient compared to the alternatives. But in simple cases, such as many of the course examples, it may not really make a difference which method you use.
