What steps can be taken to troubleshoot issues with the execution of client-side JavaScript code, like the FriendlyCaptcha script, in a PHP application?

Issue: If client-side JavaScript code, like the FriendlyCaptcha script, is not executing properly in a PHP application, it may be due to conflicts with other scripts, incorrect script placement, or errors in the script itself. To troubleshoot this issue, ensure that the script is properly included in the HTML file, check for any console errors in the browser's developer tools, and verify that the script is compatible with the PHP application.
