If you’re using Code Snippets Pro, you can select the appropriate option when creating a Content snippet, and your code will be compiled together into a single .js file that is linked in a <script> tag:

Alternatively, if you’re prefer to embed the script inline, as is often the case for tracking codes, you can select one of the two relevant options when creating a Content snippet:

Alternatively, if you’d prefer to embed the inline scripts or you’re not using Code Snippets Pro, you can achieve a similar result by adding this as a Functions snippet:

add_action( 'wp_head', function () { ?>
<script>

    // JavaScript code goes here

</script>
} );

Or for the footer section:

add_action( 'wp_footer', function () { ?>
<script>

    // JavaScript code goes here

</script>
} );
