How to use javascript variable in a laravel route?

I have a search function that returns the basic data of a user along with a generated button that should call a laravel route with the returned ID(value.id) as parameter when clicked. How do I use the value.id as a laravel parameter?

I tried creating a variable $newId and using it as a parameter but it doesn't work...

$('body').on('keyup','#search',function(){
        var keyword = $(this).val();

        $.ajax({
            type: "POST",
            url: "{{ route('search')}}",
            dataType: "json",
            data: {keyword: keyword,
                    _token: '{{csrf_token()}}'
            },
            success: function(res){
                var tableRow='';

                $('#dynamic-row').html('');

                $.each(res, function(index, value){
                    var $newId = value.id;
                    tableRow = '<tr><td><b style="color: #bb2124">'+value.id+'</b></td><td>'+value.fname+' '+value.lname+'</td><td>'+value.contactNo+'</td><td><a class="btn btn-outline-success" id="viewUserId" href="{{ route("show", '+$newId+') }}"><b class="fas fa-info"></b> <b>VIEW INFO</b></a></td></tr>';
 
                    $('#dynamic-row').append(tableRow);

                });
            }
        });
    });
