JavaScript (Internal and External)
JavaScript
can be added to your HTML file in two ways:
· InternalJavaScript
· ExternalJavaScript

We
can add JS code directly to our HTML file by writing the code inside the
<script>& </script>. The<script>tag can either be placed
inside the<head>orthe<body>tag according to the requirement.

enclosing section can be placed in the body or head of the HTMLdocument.
