How to add jQuery to a WordPress plugin or theme
If you want to add jQuery to your WordPress plugin or theme, the easiest way is to use the function wp_enqueue_script().
This function is used to add scripts to the site safely and in a way that is optimized for page loading. Here is an example of how to use it to add jQuery to your plugin:
function mi_plugin_scripts() {
wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'mi_plugin_scripts' );

It is also important to keep in mind that you must make sure jQuery is added safely and without conflicts with other libraries or scripts.
A good practice is to use the most up-to-date version of jQuery included with WordPress and use the $in_footer parameter to add the script at the end of the document.
