What role does buffering play in the execution of JavaScript and header redirection in PHP?

Buffering plays a crucial role in the execution of JavaScript and header redirection in PHP by allowing content to be outputted to the browser in a controlled manner. When using header redirection in PHP, it is important to use output buffering to prevent any output from being sent to the browser before the header() function is called. This ensures that the redirection works correctly without any errors. 

<?php
ob_start(); // Start output buffering

// Your PHP code here

ob_end_flush(); // Flush the output buffer and send content to the browser
?>
