Parameters: none

Examples:

            <p>toLowerCase() converts a string to lowercase letters:</p>
            <p id="demo"></p>
            <script>
                let text = "Hello World!";
                let result = text.toLowerCase();
                document.getElementById("demo").innerHTML = result;
            </script>

                    document.getElementById("local-2").innerHTML = "text to lower case : " + result;
