What are the best practices for outputting JavaScript within PHP blocks?

When outputting JavaScript within PHP blocks, it is important to properly escape the JavaScript code to ensure it is rendered correctly in the browser. One common approach is to use the json_encode() function in PHP to encode the JavaScript code before outputting it. This helps to prevent any syntax errors or conflicts between the PHP and JavaScript code. 

<?php
$javascript_code = "alert('Hello, world!');";
echo "<script>" . json_encode($javascript_code) . "</script>";
?>
