/ Theme Name: Your Theme Child Template: yourtheme /
Add a functions.php file in the same folder. This file will hold your code. Your child theme is ready. Now, you can add JavaScript.

function my_custom_script() {
wp_enqueue_script('my-script', get_stylesheet_directory_uri() . '/js/my-script.js', array('jquery'), '1.0', true);
}
add_action('wp_enqueue_scripts', 'my_custom_script');
Make a folder named js. Put your JavaScript file inside it. Name it my-script.js. Your theme now uses JavaScript. The code runs smoothly.
