How to concatenate without changing the existing content

Question

My goal is that by clicking the gray button adding a postit without changing what is already there, using the loop and += to concatenate will change what is already there, I wonder if there are any other options to concatenate using the loop without any changes

function enable() {
  document.querySelector('.btn-escrever').disabled = false;
}

var btn = document.querySelector(".btn-apagar");
btn.addEventListener("click", remove);
var textotitle = document.querySelector(".tarefas");

function remove() {
  textotitle.parentNode.removeChild(textotitle);
}

Answer 1

1 - the var textotitle should be within the remove function

2 - I think I’ve lived in jquery, but that would be it with him:

$('.tarefa').eq(0).clone().appendTo('.tarefas');

but I would change the tasks to id and not class because I believe there is no more than one class with this name
