How to get category URL with the slug?

Question

I have a variable that contains the slug of a category. With that slug I want to create a link to the archive page that displays all the posts in that specific category. What is the best or fastest way to go from slug to category URL?

Preferably I don't want to use a lot of variables (like when going from slug > id > url, each with a different variable). I would like a function that does one of the following, to keep the file as clean as possible.

echo get_url_function(slug) or echo get_url_function( get_id_function (slug) )

Thanks a lot in advance!

The WP function get_category_link() will do the trick.

/**
 * Gets the URL for a category term archive based on the category's slug.
 *
 * @param string $category_slug The slug of the category to get the category arcive for.
 *
 * @return string The category (term) archive URL. Empty string on error.
 */
function wpse_get_category_url_by_slug( $category_slug ) {
    return get_category_link( get_cat_ID( $category_slug ) );
}

Instead of a creating a wrapper like the example above, you could also just call the WP function directly: get_category_link( get_cat_ID( $category_slug ) )
