What are the potential pitfalls of mixing PHP code with JavaScript in a web development project?

Mixing PHP code with JavaScript in a web development project can lead to code readability issues, maintenance challenges, and potential security vulnerabilities. To address this, it is recommended to separate PHP logic from JavaScript code by using AJAX to communicate between the two languages when necessary. 

// Separate PHP logic from JavaScript code using AJAX

<?php
// PHP code
$data = array('name' => 'John', 'age' => 30);
echo '<script>';
echo 'var jsonData = ' . json_encode($data) . ';';
echo '</script>';
?>

// JavaScript code
<script>
  console.log(jsonData);
</script>
