WordPress AJAX actions

WordPress Ajax

Tasks to do:
----------------
> use actions wp_ajax_(action_name_here) & wp_ajax_nopriv_(action_name_here) to initiate functions
> you can use the same or different functions for the same purpose
> then define the ajax js file, use jQuery if needed, wordpress has jquery inside already
> use wp_localize_script('js_file_handle','name_of_object',[ 'key' => 'value ]
> the key value pair can be given primarily the wordpress ajax url admin_url('admin-ajax.php')
> define the ajax action name in the jquery, exactly like the action name in wp_ajax_(action_name_here) hook.
> write the function as needed. e.g - beforeSend, success keys in jQuery or state change in vanilla JS
> according to the defined actions, wordPress should just work fine.
