Question description

Hi, I am new to javascript and I am trying to understand a few things. I have the following scripts as examples, but I don't really understand what they do. If someone could give me a brief explanation that would be great, thankyou. 

   1) countryDropdown.init(true, JSON.parse('@Html.Raw(Json.Encode(Model.CountryViewModel.Cities))'));

        $(document).ready(function() {

            initDatepicker.initDay($(''), true);


            initSelectPicker.init($('select[name=PeopleIds]'), 'Any Person');





        $(document).ready(function() {

            $('.btnDelete').click(function() {

                $('.btnConfirm').attr('href', $('.btnConfirm').attr('href') + '?id=' + $(this).data('id'));





3) Also, in some areas I have seen references like "

    <script type="text/javascript" src="~/Scripts/init-datepicker.min.js"></script>

    <script type="text/javascript" src="~/Scripts/init-selectpicker.min.js"></script>" referenced with no other code, does this actually do anything? 

Thanks in advance!
