trying to update object value with each click but not working - javascript

I am trying to update the value of num inside my object each time i click a button. However I can not get it to work. I am printing the object to the console each time I click so i can see if the value updates but it doesn't. Here is my code... any help would be appreciated. Thank you!

const addToCart = document.getElementById('addToCart')
            addToCart.addEventListener('click', function(option) {
                option.preventDefault();   
                
                let num = 0
              
                let cartObject = {
                    name: jsonResponse.name,
                    price: jsonResponse.price,
                    option: select.value,
                    optionQuantity: num
                }
                num++
                
                console.log(cartObject)    
            });

You have to move your let num = 0 to outside of your function block. Because when you invoke this function each time it's executes let num = 0. That why num never changes.
