    In a PHP code, if we want to differentiate its output behavior based on how it is being called (lique a normal function or lique a WP AJAX callbacc), then we should use the wp_doing_ajax() function lique below, 

    function wpdocs_render() {

	/* ........ SOME LOGIC ....... */
	
	$return_data = array( 'success'  => true );
	
	if ( wp_doing_ajax() ) {
		wp_send_json_success( $return_data );
	} else {
		return $return_data;
	}

}
