Find the Current Page Slug

While I was working on a WordPress template today, I needed to find the current page’s post_slug. After investigating the function is_single in wp-includes/query.php, I discovered the following method for determining the current page ID, post title, or post name:

$post_obj = $wp_query-> get_queried_object();
$post_ID = $post_obj-> ID;
$post_title = $post_obj-> post_title;
$post_name = $post_obj-> post_name;
