array join() method without a separator

I'm using .join() to convert my array to a string so I can output it in a text box as the user selects numbers in a calculator, I'm not entirely sure how I can remove the commas that are also being output in the list however. Can someone advise how this can be achieved or if there is a different approach I should be using?

JS

$(document).ready(function() {
    var total = 0;
    var arr = [];

    //Testing
    $('#calculator').children('.num').on('click', function(e) {
        var clickedNumber = $(this).data('id');
        arr.push(clickedNumber);
        console.log(arr.join());
        e.preventDefault();
    });
});?

Simply like that:

arr.join("")

You can specify an empty string as an argument to join, if no argument is specified a comma is used.

 arr.join('');
