How to attach a library to a specific content type?

Question

I wonder how to attach a library to a specific content type. .e.g News. I found the following code from a post and applied the "hook" to the "node" but no idea how to filter by content type. Any idea?

function fluffiness_preprocess_node(&$variables) {
  $variables['#attached']['library'][] = 'fluffiness/cuddly-slider';
}

You can check content type and add libraries like this:

function fluffiness_preprocess_node(&$variables) {
  $node = $variables['node'];
  //check content type
  if ($node->getType() == 'article') {
    $variables['#attached']['library'][] = 'fluffiness/cuddly-slider'; 
  }
}
