Using a custom JQuery script in WordPress without updating the theme functions.php-CodePudding

I've added a custom JQuery script to a new JS file "themes\twentytwentyone\js\script_new.js".

And I load this new JS file in theme functions.php file.

function add_custom_script() {
    wp_enqueue_script( 
        'my_script', 
        get_stylesheet_directory_uri() .'/js/script_new.js', 
        array( 'jquery' ), 
        '1.0', 
        true
    );
} 
add_action( 'wp_enqueue_scripts', 'add_custom_script' );

This works without any issue. But is there a way to achieve this without updating the theme functions.php file? I'm not sure if updating the functions.php file is good practice.

CodePudding user response：

Using child's theme functions.php is the best practice .

But if you don't want to use functions.php then you can call js file through footer.php or header.php too.

Please note i recommend and it is the safest to make child theme for any customisation and use Child theme's functions.php.
