Example Modal Not Loading from Bootstrap

I just copy/pasted the following code from Bootstrap while following a YouTube tutorial and it will not pop-up for me. All I did was copy/paste from the site (exactly as it is within the video) but I click the button and nothing happens.

I'd like for this code to pop-up the form for users to fill out.

Any idea what would be causing this issue?

Bootstrap modals work with JS. add the bootstrap.js file as stated in the documentation

<head>
   [...]
   <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script>

Bootstrap-4 Modals make use of JQuery script.

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').trigger('focus')
})

That's why we use the below script.

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

If you are using Bootstrap-4 the above ... has to be used in your HTML file.

Bootstrap-5: Bootstrap-5 has however stopped the use of JQuery. And only two scripts are overall required now:

WORKING Demo in Booststrap-5:

<!DOCTYPE html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />

    <!-- Bootstrap CSS -->
    <link
      href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/css/bootstrap.min.css"
      rel="stylesheet"
      integrity="sha384-giJF6kkoqNQ00vy+HMDP7azOuL0xtbfIcaT9wjKHr8RbDVddVHyTfAAsrekwKmP1"
      crossorigin="anonymous"
    />

    <title>Modal</title>
  </head>
  <body>
    <!-- Button trigger modal -->
    <button
      type="button"
      class="btn btn-primary"
      data-bs-toggle="modal"
      data-bs-target="#exampleModal"
    >
      Launch demo modal
    </button>

    <!-- Modal -->
    <div
      class="modal fade"
      id="exampleModal"
      tabindex="-1"
      aria-labelledby="exampleModalLabel"
      aria-hidden="true"
    >
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
            <button
              type="button"
              class="btn-close"
              data-bs-dismiss="modal"
              aria-label="Close"
            ></button>
          </div>
          <div class="modal-body">...</div>
          <div class="modal-footer">
            <button
              type="button"
              class="btn btn-secondary"
              data-bs-dismiss="modal"
            >
              Close
            </button>
            <button type="button" class="btn btn-primary">Save changes</button>
          </div>
        </div>
      </div>
    </div>

    <!-- Optional JavaScript; choose one of the two! -->

    <!-- Option 1: Bootstrap Bundle with Popper -->
    <script
      src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js"
      integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW"
      crossorigin="anonymous"
    ></script>

    <!-- Option 2: Separate Popper and Bootstrap JS -->
    <!--
    <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.5.4/dist/umd/popper.min.js" integrity="sha384-q2kxQ16AaE6UbzuKqyBE9/u/KzioAlnx2maXQHiDX9d4/zp8Ok3f+M7DPm+Ib6IU" crossorigin="anonymous"></script>
