Is it recommended to avoid using JavaScript in PHP scripts to prevent complications?

It is generally recommended to avoid mixing JavaScript with PHP scripts to prevent complications and maintain code clarity. If JavaScript functionality is needed, it's better to separate it into its own script file and include it in the HTML document where necessary.

<?php
// PHP code here
?>
<!DOCTYPE html>
<html>
<head>
    <title>Example Page</title>
    <script src="script.js"></script>
</head>
<body>
    <!-- HTML content here -->
</body>
</html>
