Why is it important to separate Javascript code from PHP code in web development?

It is important to separate JavaScript code from PHP code in web development to maintain a clean and organized code structure, improve code readability, and enhance code reusability. By separating the two languages, it also allows for better debugging and troubleshooting of issues within the codebase.

<?php
// PHP code here

?>

<script>
// JavaScript code here
</script>
