What is the potential issue with mixing PHP and JavaScript code in the same file?

Mixing PHP and JavaScript code in the same file can lead to readability issues and can make the code harder to maintain. To solve this problem, it's recommended to separate PHP and JavaScript code into different files or use a templating engine like Twig to keep the logic separate. 

<?php
// PHP code
?>

<script>
// JavaScript code
</script>
