Boostrap Toggle Navigation bar not working

I have written the following code but I can't get a toggle navbar. When I click on the button it doesn't collapse. I don't know why it's not working. It might an error of my browser. But I don't think that so.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link
      rel="stylesheet"
      href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"
      integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk"
      crossorigin="anonymous"
    />
    
    <title>Bootstrap</title>
  </head>
  <body>
    <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
      <a class="navbar-brand" href="#">tindog</a>

      <button
        class="navbar-toggler"
        type="button"
        data-toggle="collapse"
        data-target="#navbarTogglerDemo01"
        aria-controls="navbarTogglerDemo01"
        aria-expanded="false"
        aria-label="Toggle navigation"
      >
        <span class="navbar-toggler-icon"></span>
      </button>
      
      <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item">
            <a href="" class="nav-link">Contact</a>
          </li>
          <li class="nav-item">
            <a href="" class="nav-link">Pricing</a>
          </li>
          <li class="nav-item">
            <a href="" class="nav-link">Download</a>
          </li>
        </ul>
      </div>
    </nav>

Try this:

<!DOCTYPE html>
<html lang="en">

<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js"></script>
</head>

<body>

  <nav class="navbar navbar-expand-md bg-dark navbar-dark">
    <a class="navbar-brand" href="#">TinDog</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar">
    <span class="navbar-toggler-icon"></span>
  </button>
    <div class="collapse navbar-collapse" id="collapsibleNavbar">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link" href="#">Contact</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Download</a>
        </li>
      </ul>
    </div>
  </nav>
  <br>

  <div class="container">
    <h3>Hello World</h3>
  </div>

</body>

</html>

If you don't mention the scripts order properly your navbar won't work.

As it is stated in the console error, Bootstrap's JavaScript requires jQuery.

So include this in the head and it will work just fine

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
