Get a WordPress Category ID

I rode the struggle bus pretty hard on this one today. I needed to ignore the "featured" category in a loop, and to do so, WP_Query() requires the category ID. Luckily, I found a handy function: get_term_by();

// Get the "featured" category object.
$featured_category = get_term_by( 'slug', 'featured', 'category' );

// Set the "featured" category ID.
$featured_category_ID = $featured_category->term_id;

// Get the latest three posts, ignoring the current post
// and any in the "featured" category.
$args = array(
 'post_type'              => 'post',
 'posts_per_page'         => 3,
 'post__not_in'           => array( get_the_ID() ),
 'category__not_in'       => array( $featured_category_ID ),
 'no_found_rows'          => true,
 'update_post_meta_cache' => false,
 'update_post_term_cache' => false,

// Run query.
$data = new WP_Query( $args );
