An alternate way to create the <li> elements?

Are there any significant difference between Guil's method of creating the <li> element (using document.createElement('li') and then the .appendChild() method) and mine?

const listHolder = document.getElementById('invitedList');
form.addEventListener('submit', (e) => {
  e.preventDefault();
  //My way: Create a 'li' variable and assign a string value of "<li>" together with the input value to it
  let li = "<li>" + input.value + "</li>";
  listHolder.innerHTML += li;
  input.value = '';
})

Both methods create a new element on the page, but the original method creates a new element in the code. This allows other element methods to be called on it either before or after adding to the page. In the code shown above, "li" is just a string and cannot be used to reference the element itself.

If you're certain you don't need the other capabilities, either approach does the job. In fact, you can also eliminate the variable:

  listHolder.innerHTML += "<li>" + input.value + "</li>";
