  Good job funupulu!

  Regarding your question, the rating_btn variable is a NodeList (similar to an array) of potential button elements. The forEach method loops through the NodeList and calls the callback function btn => { btn.addEventListener('click', handleRatingBtnClick) } for each item in the NodeList. btn is whatever button in the array the loop is currently on. Arrow function syntax was used here, but it could have also been written like this:

  rating_btn.forEach(function(btn) {
    btn.addEventListener('click', handleRatingBtnClick);
  });
  

  In the function body, an event listener is being added to listen for a click on the button. When the button is clicked, the handleRatingBtnClick function is called. Hope that helps 🙂
