    <script>
        var arr = ["Element 1", "Element 2",
                    "Element 3", "Element 4"];
        var up = document.getElementById("GFG_UP");
        up.innerHTML = "Array = [" + arr + "]";
        var element = "Element x";
        var down = document.getElementById("GFG_DOWN");
        function myGFG() {
        arr[arr.length] = element;
        down.innerHTML = "Elements of array = [" + arr + "]";
