JavaScript programs can be inserted into any part of an HTML document with the help of the <script> tag.
For instance:
<!DOCTYPE HTML>
<html>
<body>
<p>Before the script...</p>
<script>
alert( 'Hello, world!' );
</script>
<p>...After the script.</p>
</body>
</html>
You can run the example by clicking the “Play” button in the right-top corner of the box above.
The <script> tag contains JavaScript code which is automatically executed when the browser processes the tag.
