It is advisable to separate PHP and JS code by placing the JS library in a separate file and linking it in the HTML document. This practice helps in organizing the code, improving readability, and making maintenance easier. By linking the JS library in the HTML document, you can keep the PHP logic separate from the client-side scripting. 

<!-- In your PHP file -->
<?php
// PHP code here
?>

<!-- In your HTML file -->
<!DOCTYPE html>
<html>
<head>
    <title>Separating PHP and JS Code</title>
    <!-- Linking the JS library -->
    <script src="path/to/js/library.js"></script>
</head>
<body>
    <!-- HTML content here -->
</body>
</html>
