In the exercise we are asked to append an item to a list when a user clicks on a button. That is solved with something like the following:
$('#addNew').on('click', function(){
const newItem = $('#newRestaurantInput').val();
$('ul').append(<li>${newItem}</li>);
});
However in a real scenario many users would likely attempt to submit by clicking pressing enter on the keyboard. I wrote the following code to take that into account:
$('input[type="text"]').keypress(function(e) {
if (e.which === 13) {
let newItem = $(this).val();
$('ul').append(<li>${newItem}</li>);
}
});
My question is if there is a way I can improve this instead of having two different functions?

<form id="myform">
<input type="text" id="newRestaurantInput" placeholder="Add a new restaurant">
<button id="addNew">Add</button>
<form>
$('#myform').on('submit', function(e) {
e.preventDefault(); // use this so the form doesn't try to reload the page
const newRestaurant = $('#newRestaurantInput').val();
$('ul').append(`<li>${newRestaurant}</li>`);
});
