Hi @SamehCode01

Review how to call a function when using an event listener.

The syntax is a bit different.

Happy coding

3

i think i should call it without arguments and also without parentheses ()

4

if you write no parentheses then you are not calling the function, depending on what you are going to write that could be correct

5

ok i will try to re-read it again and again to get it

6

ok i modified the function as it required but i can’t pass still
check , here is my updated code

const happyBtn = document.querySelector("#happy-btn");

// happyBtn.addEventListener("click", () => {
//   const countEl = happyBtn.querySelector(".count");
//   let currCount = +countEl.textContent.split("/")[0];
//   if (currCount === 10) return;
//   currCount++;
//   countEl.textContent = `${currCount}/10`;
// })
happyBtn.addEventListener('click', updateCount)
function updateCount(e) {
    const countEl = e.target.querySelector(".count");
    let currCount = +countEl.textContent.split("/")[0];
    if (currCount === 10) return;
    currCount++;
    countEl.textContent = `${currCount}/10`;
  console.log( currCount) 

  // console.log(e.target.querySelector('.count').textContent.split('/')[0])

}

you need to pass a specific argument to updateCount, so you must give it an argument

can you think of a way to write updateCount with happyBtn but still pass a function (not a function call) to the event listener?

hint: it does not have to be the same function
