DatePicker not working on download 4

I want to use datepicker in my project. This is my first time using bootstrap. The problem is that the datepicker is not showing when I click the date form. I am already trying to replace the position of the CDN URL inside and inside the tag and still not working. I don’t know what mistake I am making, I hope you guys can help me with this problem, thanks.

Use this code:

$(function() {
    $("#datepicker").datepicker();
  });

Your code works well, but you need to change the format. And there is a problem in the lower sources.

I think you should add the file "popper.js" since the popup elements of Bootstrap 4 depend on popperjs.
