To link a JavaScript file to an HTML file, we use a script tag.

<html>
  <head>
    <script type="text/javascript" src="jquery-3.3.1.js"></script>
    <script type="text/javascript">
      alert("hello");
    </script>
  </head>
  <body>
    <!-- -->

<script type="text/javascript">
  alert("hello");
</script>
