Fill the validateForm function to check that the phone number contains a number (use the isNaN function) and that the user name
is less than 11 characters long. Display "Phone number is invalid" and/or "User name is invalid" in the console log if the check does not pass. Use the preventDefault function to avoid submitting the form when the inputs are invalid.

JAVA:
var form = document.getElementById("userForm");
function validateForm(event) {
var phoneNumber = form.phoneNumber.value;
var userName = form.userName.value;
/* Your solution goes here */
}
form.addEventListener("submit", validateForm);
