Where is the order stored?

I am watching a youtube tutorial, he created a function for placing order, but where is it stored? There are the JS function and the view.

function order(){
    var msg = note.value;
    var orders = localStorage.getItem('orders');
    var ur = '/cart/';
    var orderData = {};
    orderData['orders'] = orders;
    orderData['note'] = msg;
    $.ajax({
        url:ur,
        type: "POST",
        data: orderData,
        success: function(data){
            window.location.replace('/success')
            localStorage.setItem('orders', JSON.stringify([]));
            localStorage.setItem('total', 0);
   
        }
    })

}

def cart(request):
    request.session.set_expiry(0)
    if request.is_ajax():
        request.session['note'] = request.POST.get('note')
        request.session['order'] = request.POST.get('orders')
    return render(request, 'cart.html')
