            }
        }
        e.target.value = "";
    }
}

input.addEventListener("keyup", addTag);

const removeBtn = document.querySelector(".details button");
removeBtn.addEventListener("click", () =>{
    tags.length = 0;
    ul.querySelectorAll("li").forEach(li => li.remove());
    countTags();
});
