What is Slug?
A slug is a URL-safe, human-readable identifier for a resource — typically lowercase, with spaces replaced by hyphens and special characters stripped. Slugs are preferred over numeric IDs in URLs because they are descriptive and good for SEO (e.g. /blog/what-is-a-slug instead of /blog/4821).
Example
"What is a Slug?" becomes the slug what-is-a-slug.
