问我正在用javascript做一个计数器。有人能告诉我如何在这里“循环”，这样每次有人点击按钮时，计数器就会增加吗？

EN

const count = document.querySelector('.count');
const addBtn = document.querySelector('.btn-add');

// Call a function that returns a new function that works
// as the click handler
addBtn.addEventListener('click', handleClick(), false);

// Initialise `add` with an initial default value
function handleClick(add = 0) {

  // Return a function that is called when the
  // button is clicked. That function (closure) will keep
  // a record of the `add` variable,
  // and update the content with its value when the button is clicked
  return function() {
    count.textContent = ++add;
  }

}

<div class="count">0</div>
<button class="btn-add">Update counter</button>

let addBtn = document.querySelector(".btn-add");

addBtn.addEventListener("click", function () {
  let count_element = document.querySelector(".count"); //select element with class "count"
  count = parseInt(count_element.innerText); //parse the text inside count_element to int
  count = count || 0; //if count Not a number, initial value of count is 0;
  count = count +1; //add 1 to counter
  count_element.innerText = count; //change count_element text to count
});

<button class="btn-add">ADD</button>
<div class="count">NaN</div>
