My "else" statement does not work. It keeps showing the "if" statement's alert even if it's below 14

  function buy() {

    let name = prompt("What is your name?");

    let age = prompt("How old are you?");

    if (age <= 14) {

        alert("Hey, " + name + "! 😁 Have fun buying on our site! 😋");

    } else {

          alert("Sorry, " + name + "...😅 You are too young to buy on our website. You might have to ask your parents. 😬");

    }

  }

  let buyButton = document.querySelector(".buy-button");

  buyButton.addEventListener("click", buy);

<button class="buy-button">Buy Button</button>
