What is the purpose of wp_ajax_* actions in plugin development?

Answer: The purpose of `wp_ajax_` actions in WordPress plugin development is to handle asynchronous requests (AJAX) sent from the client-side to the server. They enable developers to perform tasks such as fetching data or processing form submissions without refreshing the page, enhancing user experience. These actions are specific to logged-in users, while `wp_ajax_nopriv_` handles requests from non-logged-in users.
